Windows upgrade from Vista. Upgrade worked fine until recently(possibly after an automatic update) Problem is when I try to open a folder I get a message that: Windows has stopped working. Gives me the option to search for a solution and restart or just restart. Details on this are listed<>Event name:APPCRASH Application name: EXPLORER.EXE Application Version6.1.7600.16450 Fault Module frame:EXPLORERFRAME.dll This problem seems to be increasing. I have Norton security provided by Comcast. Ran all scans numerious times. Have Registry utilities pro by Avanquest, ran that several times. Did not help I am getting frustrated with this problem. Anyone know what to do?
