I have just installed IE 7 on top of IE 6 and in certain applications I experience problems, the main area being Email (yahoo). If I try to open the address book the screen for the address book will appear blank and everything freezes, including windows task manager, after a few minutes I am able to use task manager to kill the address book window which in turn kills the Email window. If I try to open an Email in a new window most of the time it freezes, sometimes if I wait long enough (10-15) Min it will self heal. Any time I am in an email that contains a link, if I try to follow the link the windows will lock up. I can open Email in the same window but again I cannot follow a link. Occasionally when things do work and I close out the window with the Email message I find a smaller second blank IE window, sometimes when things don’t work I find a second smaller blank IE window. Help
