Intermittent Lockups

[HalfCyborg]

I am having problems with intermittent lockups. I keep UR minimized in my tray at all times. Lately, it has started refusing to respond. When I try to recover by right-click, close it, I get this message in a pop-up window:

"The program can not be closed. If it is being debugged, please resume it or close the debugger first."

The only way I can fix it is to log off windows to force it closed. I have tried a compact/repair to no avail. My db is fairly large but not huge (175 MB) and it consists mostly of saved web pages.

The problem may manifest itself in 5 minutes or 5 hours. If I leave it open overnight it is always stuck in the morning.

Is anyone else having similar problems?
