yeah...it would be nice to know which applications are generating errors for you, or what's going on when you get them.

You can also check the Event Log to find out what's causing hangs, it can often tell you specifically what's wrong, also submitting
error reports can help. If it's a device driver or something like that, it'll usually tell you.
