I am running XP Pro, SP2 and for some reason IE will no longer launch. I was using the browser, hit Ctrl+N to open a new window, and my IE window closed. When I tried to relaunch nothing happened other than a brief appearance by the hourglass - no error messages, no event log entry, nothing. I've rebooted, reinstalled IE, and scanned for viruses, but nothing seems to work. The weird thing is that if I open up Windows Explorer and type a URL in the navigation bar I can access websites without any trouble. However, clicking on a link that tries to open a new browser window or hitting Ctrl+N will cause the window to disappear. Help!
