Alright, I confess, mainly because I can't figure out HOW this is happening, but it happens so irregularly, and with such a long interval between events, that trying to figure out why it's doing this is plain annoying. Mainly because the fix resets ALL folders.

Mainly, I'll find that the Web View gets turned off on ALL folders, and I didn't do anything to the machine between last night and this morning. (24/7) When I left last night, everything was working OK, all folders displayed the Web View. This morning, Surprise, Surprise, Surprise, no Web View anywhere. Any bloodhounds here offering any pointers?
