Rogers yahoo site - when I go to change my password the page is hanging. While loading the page, the number of items remaining freezes
at usually "2 items remaining" and the progress bar never completes. Therefore I have to use my Wife's PC to change my rogers yahoo password.

I only see this http://support.microsoft.com/default...;EN-US;Q818506 for IE6. But nothing for Win7, IE8. I have also check the security settings on the other PC that works and changed mine so maybe it's Norton which I have.

Is there still a setting I need to turn on/off?
