I am running a new Lenovo desktop PC with Windows 7 and Office 2007. Everything has been working perfectly since I got the computer about a month ago. A few days ago I started having problems with Internet Explorer (version 8). Almost every time I try to run the program it hangs on the opening screen (never getting to anything beyond a blank screen). When I go to Task Manager to end the process there are two versions of iexplorer32 in my Processes list - which I am able to delete to terminate the program. My Firefox (which I keep as a backup browser for situations like this) works fine. All my other programs work fine. I have run my Norton Utilities and Norton Internet Security scans without finding anything to account for this behavior. Any suggestions?
