    Default System under high load unusable?

    Hello there,

    Actually quite normal, just like it was with OpenSuSE 11.0 under 'high load', well, probably load isn't the right word here

    I just had this problem and thought it was a kde4 update problem. I update a few times a week, so I can't point to any one update. But, a few days ago, my mouse started to hesitate and then the keyboard. I stumbled onto the solution: kill boinc.

    I have been running the same boinc version for months. This problem popped up after a recent update and I don't know how to fix it. I seem to have installed a newer version of boinc than is found at the univ. Berkeley site or in the repos. I have been away from the computer for hours with only boinc running. It shows 17 minutes of cpu time.
