Sometimes, occasionally, Firefox just hangs, and the whole system refuses to respond to any keypresses or mouse clicks. If I do Ctrl-Alt-Del to get task manager, I can cause it to kill the process which I THINK is causing the problem. But a lot of the time I get the response that the process is "waiting for a response from me", although no such thing is visible. In such cases, I often find (when I get things straightened out a little) that Firefox had popped "up" the message box asking about "close multiple tabs" -- even though I had not to my knowledge tried to close anything. But what is worse: the message box had not popped up but rather popped under, so I could not see it! So I can't respond to the message box because I can't see it, and I can't get to it (assuming I know it is there) because I can't minimize or move any of the windows (since system is totally unresponsive). Has anybody reported such a thing? What can I do. I am almost ready to remove firefox because of this, and my wife is even more frustrated and has threatened to destroy her laptop in a rage.
