I have Windows XP on my machine. Ever since I dowloaded the updates for Windows XP, Internet Explorer has been locking up on me. When I launch the browser and do a search from MSN home page. Or any search engine. When it displays the results, IE will pop up another window (advertisment)this always locks up. I would have to end task on IE. I tried uninstalling, and reinstalling IE from the Windows XP CD and I still get the same error message. Does anyone have any ideas of how I can stop this from happening?
