Internet Explorer 5.5 began to cause a fatal exception error whenever I shut it down (click X at top right hand side of screen.) I first noticed the same problem when closing down WinMX (a peer to peer file sharing program like Napster.) I totally un-installed WinMX, then noticed the same behavior when shutting down IE5.5. I have: run Scandisk(no fix), reinstalled IE 5.5.(no fix), Installed IE6.0(no fix), removed IE 6.0 and re-installed IE 5.5. There doesn't appear to be a way to completely remove all traces of IE before I run Scandisk, so I can get a completely fresh install. IE only allows you to revert to a previous version when uninstalling. The problem must be with IE, because Netscape works fine. IE works fine too, until I try to shut it down. Does anyone have a suggestion? Thanks in advance. MrPB
