How long did you wait when the system "crashed" with the mouse still working? This sometimes
only means that some thread has grabbed the system resources while waiting for some response. (Often a network response.) I've had to wait as much as five minutes (less that once in three months) for the lock to be released.
Once I got impatient and hit the "reset" button. When I rebooted, I discovered that the "wait" had been for a block write to my ext3 journal file, and that a (now bad) journal file trashes the whole file system. (You can delete
the bad journal file, making the file system ext2, but it's a real pain, and you may have bad data in you main file. I ended up reinstalling FC4.)
