This system stays on continually, but with a screensaver activated. Although the monitor and speakers are turned off if the system is going to be left unattended for long periods, the screen saver is still enabled. Since installing BitDefender 2010, occasionally when attempting to restart my session I am completely locked out. The screensaver shows on the monitor, but no amount of moving my tablet pen, repeatedly hitting the Esc key, or repeatedly clicking the Crtl-Alt-Delete key combo has any effect. All I can see is an hourglass icon overlaid on the sreensaver image. I've left it on for a half hour like that with no change, just the hourglass frustratingly sitting there.
I thought it might be my defragmenting program getting hung-up by BitDefender, but I have no way of knowing. All I can do is hit the reboot button on the computer box. Is there some way to log what is hanging at the point of the reboot? How do I keep BitDefender from locking up my system this way? If it happened all the time, it might be easier to figure out, but the system can exit the screensaver program normally for days at a time, then — Poof — locked out. I've used the same screensaver with the same system (XP Pro sp2) for years with no problem, so it is not the screensaver.
