Sometimes I get some 'lag' where the cursor doesn't draw for a few seconds but it always fixes itself. On my system sometimes P6 appears to hang with the Windows hourglass up. The first time I gave up and did a Ctrl-Alt-Del to reboot, but when Task Manager popped up the hourglass went away and everything was fine. shrug. A little screwy but Ctrl-Alt-Del and then cancel Task Manager works every time on my system for some P6 problems.
