Hi all,

i've installed boinc 5.10.42 64-bit on my Vista PC. The Boinc Manager is configured to "Do work only after computer is idle for 5 minutes".
After 5 minutes idle time, boinc starts but after another minute or two it suspends the computation with "user is active" messages, which i'm not. Then after 5 minutes idle time it resumes the computation just to stop after 1/2 minutes again....

Is this a known problem? Can the screensaver cause this?

Yes, it can. Especially if you have an on-board graphics chip on the motherboard, instead of a dedicated external AGP, PCI or PCIe card.

Then the CPU will also take care of much of the graphics, which BOINC may confuse as user being active since something is using the CPU.

Good to know.

Is there no way, that the Boinc Manager under Windows just depends on the activation of the screensaver? The actual behavior is a litte bit non-productive. :-(
Which factors are responsible for detecting user activity?

BTW I have an external graphics card.

version 5 of BOINC isn't to Vista friendly. Version 6 is in early development and will have much greater support for vista and also run much more securely on all windows OSs.
