Thanks, that was "interesting"..., but also just a little scary! I didn't manage to read what would happen before my fingers already had clicked Start, so I got nervous when Explorer was closed, thinking it was crashing. But no, it was meant to close. However, it did not restart, though it was supposed to. I rebooted Vista and now Explorer is well, again. Several temp folders were cleansed, but C:\Users\Curt\AppData\Local\Temp has not been touched. It is now 2677 files and folders.
