I've noticed the statistics page on this site.
Looking at it, i see i'm currently bussy with 2 workunits, i have a laptop and a desktop.

However i notice at my desktop screensaver is at 97%
While when i login i'm at 6%
So apperently, screensaver is running as a different user?, however it is not in myy stats (there i see only my laptop and my desktop two current jobs.

screensaver mode should i think on both machines count to... or do i miss something here?
(latest boinc version and cable modem)

It seems to me that this is again an issue of the new 5.59 rosetta version which introduced a new way to calculate the completition percentage.
I see you set rosetta to run 3hours/WU (default value), I would rely on that factor to see how much work has been done.
Next time you see the problem, check the time it's already running ("CPU time") and compare it with the two percentage values.

By the way: the screensaver uses a small percentage of your CPU, if you disable it, you may get more credits/day. (The scientific work of rosetta doesn't depend on the screensaver)
