		<description>Mark, how brilliant!  lol.  I thought perhaps any date before 11/24 would also work, but no go with 11/1/2009, either.... What an odd bug.
Thanks again for your post and bringing even a popcap developer into the discussion.  This has been great!</description>

		<description>I&#039;m sorry to have to say it, but this is going to have to be my last post on this subject.  It&#039;s starting to seem like a mistake that I responded in the first place, even though I was only trying to help.

We are absolutely slammed trying to make this game better for millions of people.  I don&#039;t know if you guys realize how truly tiny a slice 64-bit Linux is for our product.  It&#039;s way less than a tenth of one percent.  To give a sense of perspective, we generally don&#039;t support browsers with less than 3% usage because we need to focus on moving the game forward for the extreme majority.

I totally understand you guys wanting this problem fixed.  I do too.  But again, this is not a problem with our codebase.  This is a problem with the Adobe Flash player on 64-bit Linux.  If you guys have an investment in seeing this bug fixed, Adobe seems like the right place to lean on.

I&#039;m sorry I&#039;m not able to help further.  I wish you all the best.</description>

		<description>Hi there Akos,

I&#039;m sorry to hear that.  Though I have to admit I don&#039;t understand why you would discourage people you care about from playing games they would most likely like, all because one of our free web games doesn&#039;t run on a corner-case environment because of a bug in Adobe&#039;s Flash implementation on that platform.

But I guess that&#039;s your choice to make.  I wish you the best.

		<description>Hi Scott,

thanks for the honest reply, I do appreciate it.  I definitely agree with you on the technical part.  Waving off a &quot;tiny slice of your user base&quot; is PopCap&#039;s decision to make, and I see your reasons.  My decision is whether to ever buy anything from PopCap, or recommend to any friends either on Facebook or outside of it.  This way the answer is an easy and obvious no.</description>

		<description>Hi Akos,

I can&#039;t tell you why it would juggle between working and not working, other than the reason does *not* lie with us.  We did not update the code to the game in the specific timeframes mentioned, and we have certainly not touched the randomization code in any way since we launched the new Blitz.

My best guess:  Since the randomization seed inside of Flash is tied to the timer, it seems plausable to me that something about the time values could be conditionially triggering the bug.  That could explain why it works at some times and not others.  But that&#039;s purely speculation, of course.

It&#039;s overwhelmingly clear from the feedback in this thread that this problem is isolated to 64-bit Linux.  We have yet to have a single report from any of our millions of players that they suffer this problem on another OS.

And I hate to say it, but we both can&#039;t provide a fix (because the problem isn&#039;t in our code) and we can&#039;t justify spending any more time investigating this issue on this platform.  I hope you understand it&#039;s hard enough to find the time to make the improvements we want for our millions of players that we can&#039;t afford to get bogged down in any such tiny slice of our user base.

Sorry I don&#039;t have anything better to tell you...</description>

		<description>I forgot to add, that since Monday, I tried both 10.0.32.18 and 10.0.42.34.  Bejeweled is working with neither (besides that board from hell :) ).</description>

		<description>Hi Scott,

thanks for following these comments.  Please note that I am trying to help here, not trying to bash PopCap, or anything like that.  Of course, I would love it if BB worked.

Anyway, I looked at my emerge history.  I had the same flash version (10.0.32.18) from Aug 4 to Dec 14.  During this time, you launched the new version, which worked for a while, then stopped working near the end of October, then started to work again sometime in the middle of November.  I am 100% certain nobody touched the adobe flash player on my computers during this time.  The problem manifested on all 64-bit Linux computers, and there was no problem at all on 32-bit Linux machines and on Windows (which I don&#039;t use unless I have to).  So it is entirely possible that the flash player is at fault here, especially since the 64-bit Linux version is a bigger pile of junk than usual.  But then please tell me what might be the reason for it continuously working for a month, then continuously not working for another?

If there is any way I can help you guys debug this problem, please tell me.  (Also, if you don&#039;t want to bother with 64-bit Linux users, that&#039;s OK, too.  Tell me, and I won&#039;t bother either.)</description>

		<description>Honestly guys, we aren&#039;t changing code back and forth.  We have not touched the randomization logic since the new version launched quite a while ago.

If the board is sometimes working and sometimes not, maybe that&#039;s somehow related to the nature of the bug in the version of the Flash player with the problem?</description>

		<description>My board looks exactly like the one on your screenshot.

Using Debian squeeze, 64-bit; Flash 10.0 r32, I don&#039;t know if it&#039;s 32-bit or 64-bit; happens in both Iceweasel (rebranded Firefox) and Konqueror.</description>

		<description>Just to chime in; I was still running the older 10.0.22 version of the 64-bit flash alpha release, and still started experiencing the &quot;same board&quot; problem at around the same date Mark&#039;s post mentioned, so it doesn&#039;t have to do with any recent updates to the flash platform at least...

So, nothing on my end changed at all [no OS updates, no ff updates, no flash updates] when the game started to show me the same board.</description>

		<description>I recently updated flash [the 64 bit alpha] from 10.0.22 to 10.0.32.18 on Debian lenny Linux 64bit with firefox 3.5, but alas, I still get the exact same board you posted above, every time.

I figured it must have had to do with me being on ilnux [also the reason the bejeweled folk haven&#039;t answered my problem report, I assumed], but my old 32-bit ubuntu hardy laptop generated new boards just fine.

Thanks for this post, Mark!  It was more information than I had hoped to find out there! :]</description>

		<description>It only seems to be happening on 64-bit Linux (Flash version 10.0.32.18, Firefox 3.0.14 on Gentoo Linux).  On 32-bit Gentoo Linux, with the exact same versions, everything is OK.  64-bit Vista is also OK.

Also, for me this started around 23-24 October (I&#039;d guess 23rd), definitely had no problem before.</description>

		<description>I am also using 64 bit flash 10 64 bit linux(Fedora 11).  I am encountering it on two machines that are running the 64 bit flash.  I don&#039;t think it was happening after the initial release of the new version of Bejeweled, but I can&#039;t prove that.</description>

		<description>I get the same board on my Bejeweled .....  Every time......

Firefox Browser, with Flash 10  on 64-bit Linux.  Maybe a Flash bug?</description>

		<description>Ah, so you&#039;re using Linux as well.  I can only assume this is a problem specifically with the Flash Player on Linux+Firefox.  We&#039;ve only seen 2 reports of the problem so far (yours and one other), but both were on an OS/browser pair that is quite rare when it comes to Blitz players.  That seems too specific and too statistically unlikely to be coincidence.</description>

		<description>Being a Bejeweled Blitz addict, I played that game zillions of times but didn&#039;t even notice that the gems on the board wasn&#039;t reshuffled. Oh well...my score is still the highest among my friends so it doesn&#039;t relly matter if someone was cheating at Blitz. :P</description>

		<description>Thanks Scott. I&#039;m still seeing the same error here at the moment, so if the code has been unchanged for weeks, that strongly points towards the flash platform itself (which is Adobe Flash 10.0.32.18 for Linux running in Firefox 3.0.14 here on my Debian Squeeze system).</description>

		<description>Hey there -- Scott Lantz from PopCap here.  Just wanted to let you know that we saw this and are looking into the problem.  We definitely do seed the random number generator with the current timer, but for some reason in some cases, it appears the timer value reported by Flash is 0.  That appears to be the case in the screenshot of your initial board state (given that a seed of 0 always looks the same.)

Also, if people are seeing this issue intermittently or are seeing it fix itself, that&#039;s odd given that we haven&#039;t touched the code since we launched the new Blitz 3 weeks ago or so.

We&#039;ve haven&#039;t ever seen this internally and haven&#039;t been able to reproduce it, but we have received one other comment recently about this.  Would you mind sharing your OS and browser information with us?  The one other case we know of is happening on a Firefox alpha build on Linux.  Also, I would be curious if the problem would somehow fix itself if you were to try a different browser.

Anyway, of course we&#039;re delighted to see people playing Blitz, and we&#039;re sorry you&#039;ve been having these issues.  We are looking into it, and hopefully we can figure out an alternate method that isn&#039;t subject to whatever is causing this problem.

Cheers,

		<description>The game starts differently every time for me, which is a pretty good counterexample. It&#039;s possible that you have a library from either Flash or from your OS that has a randomness flaw. If so, the implications there are worse than making a game no fun. If any crypto functions use that same library, you&#039;d be losing randomness for encryption.</description>

		<description>It&#039;s possible, but there&#039;ve been reports of the same thing from others who&#039;ve then noticed it being fixed in the game. Popcap may have noticed the problem and solved it.</description>
