ooohhh, I've been testing my computer for the last 3 weeks for this very thing. I *usually* get all the way to my desktop and then it freezes after say 1 minute or so.
I've checked my RAM, no problems. All my drivers for everything are updated and I have the newest versions of everything.
I've run a full virus scan, Ad-Aware, Spybot and MS Antispyware scans...nothing.
I've been playing around with loading different apps at start up to see what happens.
I always have ZoneAlarm and AVG run.
Never freezes with just Windowblinds running. Windowblinds and Right Click=freeze, Windowblinds and Workshelf=freeze.
It's taking a long time (3 or 4 days per new setup) there are a jillion different combinations.
I will let you know if I nail anything down. Glad you brought this up...I was going to write all this after I was finished testing.
