I have IE7 at work loaded on XP Pro. It works great. I have had absolutly no problems at all. I loaded it on my home computer using XP Pro through a wireless router to a DSL modem. I also worked without any problems at all. I recently loaded RC1 and have had severe problems with IE7. I thought it may have been because I used the upgrade option so I followed up with a clean install. Vista is working well with the only problem being that it doesn't recognize my sound driver. It loads but there is no sound. Anyway, to return to the subject; IE7 is constantly timing out. I cannot get to any of my 3 web based e-mails nor can I use the windows mail to check my bellsouth mail. I have tried to download IE6 so I can delete 7 & re-install but I cannot get to Microsoft's download page. I also cannot get to CNet, TuCows, or any other of the usual trusted sites I use. I also cannot get to any site with the prefix "[URL]http://go.microsoft.com/fwlink/?linkid=[/URL] ". Any suggestions would be greatly appreciated.
