Started a few days ago, when awakening fromo screen saver/inactivity the toolbar is gone and nothing responds. The mouse moves, I can click on an icon, it will darken and the curser goes to hourglass, but nothing happens.
Ctl/Alt/Del won't do anything, Windows key, nothing.
I end up holding the power button til it turns off, then hit it again to restart.
I first thought it was something in Firefox as I usually have it left open, but today it was just my normal desktop.
I run Boinc as my screensaver, I should perhaps disable that for a day or two and see it that makes any improvement.
This is a dell Opti GX620 4 G ram running XP Sp3, Zone Alarm and AVG.
