$o |>0/|/3, how many people address you by your "name"? :-P

I agree, but apparently didn't say it, that the issue seems to be CUDA vs. SETI (to oversimplify for brevity). Interestingly though, I don't recall seeing this issue when Einstein uses CUDA. Maybe just because it's a less complex graphics job (or so it seems to me).

Unfortunately I haven't been able to further test with the BOINC screensaver disabled, because it's been very windy around here lately and I'm afraid to leave the computer on when I'm away for long periods -- too often the power goes out, and I have no UPS. When the weather returns to normal (or when I get a battery backup) I'll be back to running 24/7 and can see if my change removed the problem.

Thanks[/i]

Thanks Ageless, that certainly sounds applicable. I had searched that error phrase on Google but wasn't able to find anything as useful as the info you sent.

Right now (as I'm again running 13 tasks) there's about 6300 MB of available RAM. But I'll check it from time to time, especially after the error appears, if I can... I think even Ctrl-Alt-Del once failed to respond at that point.

Haven't yet checked any system logs. Oh, and yeah, I'm under no illusion that even 12 GB of memory can never run out -- especially the way I multitask! :-)

I also noticed that Einstein, not SETI, is using my GPU right now. It's quite possible that this happens only when SETI is using the GPU.

Anyway, several hours have passed (overnight) without incident, so I'm hopeful that the change of screensaver took care of it. Still watching and waiting...

Thanks Jim,

You know, that hadn't occurred to me, even though I had disabled the screensaver on at least one previous computer. I've taken your advice and have disabled BOINC as a screensaver -- opting for "Ribbons" instead. :-) Like you, I seem to recall a screensaver issue with an earlier version of BOINC, or even the original S@home application.

Time will tell if that solves my problem, and I'm still eager to learn more, so more input is welcome.

I also thought about suspending SETI for a while, but for whatever reason haven't gotten around to trying that. I guess I'm hesitant to stop processing data for the length of time it might take to be sure I'd found the cause (two or three days, I figure, to be certain). Probably a lame reason... but anyway I like your idea better.

Oh, and what is an "optimized" app?

Hi everyone,

This may be the first question I've posted in my eleven years with SETI@home.

I'm running BOINC on a Windows 7 machine with 12 GB of RAM and a 6-core Intel processor. The NVIDIA graphics card is CUDA compliant. In BOINC Manager under Activity, I've selected Run Always and Use GPU Always. (I can provide my other settings if needed.)

To my delight, the system usually seems perfectly able to handle these settings; I'm able to watch TV, do malware scans and use my browser while typically running 13 tasks at a time (SETI, Rosetta, & Einstein). But for the last several weeks I've been getting a strange message... a small box in mid-screen that's likely to appear if I've been away from the computer for more than a few hours, and which says simply, "failed to register the window class."

When I slide the mouse to click OK, it vanishes before I can even click it (only to come back after I've walked away again). But after I've seen it, many programs fail to work, including Windows Live Mail, Paint, my TV application and more. I have to reboot to get normal functioning back. IE and Firefox seem unaffected.

I suspect, but am not sure, the problem is caused by SETI@home because I've seen some strange behavior on the screen when the SETI screensaver is running... another message that blinks on and off repeatedly and too quickly to read, but which appears to say, "too many errors have occurred..." If memory serves, it alternates (very rapidly) with the screensaver, as if they're fighting for dominance.

Another clue: it all seems to have started around the time I attached BOINC to SETI. (I'd already been attached to Rosetta and Einstein, and don't recall this issue then.)

Could I be right about SETI causing this strange message? And what can I do about it? It's become an almost-daily routine.

Thanks so much.

Thanks Eric and Pappa. It's gratifying to see that my guess about what could be done -- based on only slight knowledge and logical deduction -- is not only plausible, but is already underway.

This seems like the kind of thing that should be fixed, if commonplace, because you're cheating yourselves of possible donations...


If the user's browser doesn't have the CA listed as a trust, how does SETI fix that?


That's a good question and I don't know the answer. (As I said above, I don't really understand how certificates work.) But it seems to me that communication to the certificate authority (COMODO CA in this case) about their "unrecognized" status would be a good start. They could then complain to the Mozilla community and to the creators of any other affected browser.

Hi Eric,

I don't really understand how certificates work, but I ran into this exact same problem. I checked your hash numbers and all the rest -- it all matches what I'm seeing on my screen -- and I trust the site, so I'll make a certificate exception.

But just so you know, I also have Firefox 3.6.12.

This seems like the kind of thing that should be fixed, if commonplace, because you're cheating yourselves of possible donations. If I weren't so patient and so dedicated I may have deemed it not worth the effort of researching this and checking those long strings of characters. I've been with the project since '99 and I'm not giving up that easy.

Anyway, thanks for the instructions -- and thanks to Dune for the screenshot.
