I've begun testing Flash 10 within IE7 on a few xp boxes before deploying throughout the department. After installation using the online ActiveX installer (as admin) IE7 becomes unstable, sometimes freezing while loading pages containing Flash. Examples are espn.com and adobe.com. I redirected the testing computers around our proxy to ensure that wasn't the problem. We are adopting a long list of GPOs from Active Directory, however, which I assume to be the problem, since our laptops (who don't get GPOs) haven't been displaying this issue. The GPO "User Config -> Admin Templates -> Windows Components -> Internet Explorer -> Administrator Approved Controls" is left as Not Configured. Any idea of other GPOs that might be interfering with the proper installation or operation of Flash 10?
