Updated our imac to Mountain Lion, but now ap store won't open
Just updated our iMac to Mountain lion. The app store shows it has one update, but I can't open the app store. It won't us sign on, minimize the page, nothing. All I get when trying to open it, is the icon goes in the doc. No windows at all.
Please help!
iMac (Flat Panel), OS X Mountain Lion (10.8.2)
