Not sure if this is already mentioned anywhere, I'll post it anyway. ;-)
Normally I don't abort WUs after all and let them run.
But in the past days I had to abort some because of different reasons.
They were all already running for a short time, but every time on aborting a WU a windows pop-up error message appears and says "SunflowerBlender doesn't work anymore".
This behaviour is annoying. The program should exit normally. Can you do something about it, Janus?

Yes, this is a longstanding issue. It happens somewhere inside the BOINC code and has been with us ever since we switched to multithreaded GLUE3 a year or so ago. The crash occurs after we have let go of control to BOINC but before the app actually exits so it looks like it is GLUE that errors out when in fact GLUE does the right thing.
It happens on all platforms - on Linux it is a segfault.

Recently David cleared up some undocumented behavior related to multithreading and BOINC wrapper apps that I think may be related. Once the final licensing stuff is resolved regarding Blender 2.6x and the new clients then the fix that will hopefully fix this is going live too.
