I'm having this same problem, and I don't really think it's quite what everyone seems to think it is. This is a fairly severe hiccup when it occurs and it happens every few seconds. I do not see the problem with all programs, but I do see it when watching any sort of video or playing many games. From the games, I can tell you it's bad enough that it misses keystrokes - that's a fairly long glitch.

While I totally agree with the first post - we should have these settings available - none of them will fix this problem! At least not from my own testing. I've tried all of the following in the BOINC prefs with no appreciable change:

Use only one core instead of 2.
Set CPU usage down to 50 percent.
Increase write cycle time to several minutes.

I've also set the CPU affinity manually in Taskmanager to make sure the BOINC stuff and the desktop program were on different cores. I've tried running the games at above normal priority. I get the same glitch with both Seti and Einstein, so I don't THINK it's specific to the apps.

I don't experience any such behavior under Win2K on the very same box. It's only when I boot into XP64. I'm relatively certain it's a 64bit scheduling issue of some sort, but whether that's in Windows itself or BOINC, I couldn't say. I'm probably going to do a clean install in a few days at least for testing, but I noticed this problem almost immediately, so I don't think it's a normal type of conflict issue with AV or other background software.

The only other thing running that I suspect MIGHT be the culprit is I'm running Intel's Matrix RAID. That's one possibility I'm going to try and eliminate soon. I'm also going to try XP32, but I'll be very surprised if I see the problem under that OS.

Just for the record in case others can help come up with commonality:

Intel E6600 Core2Duo
Asus P5B-VM DO (Q965 chipset w/ICH8DO)
2Gig Dual Channel RAM

Free software that makes the problem very obvious:

VLC media player
"Echoes" from binaryzoo.com (neat game btw)

I'm getting rather tired of clicking that little snooze button, so suggestions are welcome!
