Flash 10 and IE7 instability caused by GPO?

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?

FWIW--I installed Flash 10 a few days ago and have no problems accessing Flash content including that on espn.com.
Are you saying everything worked OK using Flash 9 but that the GPO changed at the same time you installed Flash 10?
It is a little hard to address your question without knowing the new GPO's.
This may be a question for Adobe.  They maybe worthless unless you are a good customer.

Sorry if I wasn't clear: The GPOs have remained the same. Viewing said sites with Flash 9 works fine, but viewing with Flash 10 is highly unstable (for IE). Uninstalls and reinstalls of Flash 9 and 10 on multiple machines have confirmed this oddity. So what GPO would affect 10, but not 9?

Do you have a firewall with some sort of HTTP filter? I would look at flash content types filtering as a start.

No, that would affect our laptops as well. I can only come up with a GPO problem, or perhaps just a weird problem on our Ghost image. I'd hate to have to start over the install image from scratch just for a Flash plugin.

After deep investigation, it appears Flash 10 downloads files a little differently, so many proxy servers implementing a download blocker will cause the Flash 10 plugin to become very unstable. *Note that this is the case even if the computer is set as a machine to be ignored by the proxy.* In this case, the proxy software is ClarkConnect.
