I went to IE 9 upgrade just about when it became available . Virtually no Iternet explorer has stopped working warnings. Also seems to work fine in compatibility mode when needed.
I installed IE9 Beta a long time ago. Works great. Now they want me to upgrade to IE9 and my beta version won’t allow me to complete the install. I’ve tried several methods to eliminate IE9 Beta, but I can’t. Even all of the MS support help can’t get ride of the Beta version.
I’ll just live with the Beta and no upgrades from now unitl I do a clean install.
