Just downloaded the new screen...wow! way cool!

Help,
I am having a problem when I quit a session and try to run Mach 3 again? It locks up my computer. I can't even Ctrl-Alt-Del and and get the task manager. It even freezes my mouse. I have to shut the power off and reboot. The screenset does not have anything to do with it, it happened on the old 1024 set too. Any Ideas?
