If so, start by removing all IE addins. These are called BHOs which you can remove in a flash with the tool called HIJACKTHIS. Don't remove anything but the BHO entries.
My wife does medical transcription and the company requires IE6 instead of IE7. There was no uninstall option on IE7 on Add or Remove Programs. The company told us to uninstall Service Pack 3 and then we could uninstall IE7. That would reinstall IE6 which it did. We then reinstalled SP3. Now, explorer opens but hangs up. Will not open my homepage. I am using XP Small Business edition.
Thanks to anyone who can help.
