I've also seen Prime95 lock up on various machines. In my experience it
happens when trying to send a result in to the server and for some reason
the sending fails (I pretty sure this has happened when the server was up,
but I can't be 100% sure). The worktodo.ini isn't empty, but the processing
thread stops doing anything. The UI thread continues to execute. Most if
not all machines I've seen this on are running Win2k Prof. with Prime95
running as a service. Stopping it running and starting it again has always
solved the problem, however, on odd occasions the only way I could get it to
stop was to reboot the machine.
