I was running the beta for awhile and needed to remove it as there were too many issues with webpages not working properly and activex controls not working at all. I would remove the beta and stay with IE7 for now until they fix more of the issues. I would also report the issue to Microsoft so they are aware of it.

I believe it would be more accurate to say it will not work "in the current beta version of IE8". I know that is what you mean, but I don't want to mislead readers of this thread xx months from now when IE8 is actually out there and when it may (I hope and expect) work! 

As I post this, it is now September 2009.  It's still not fixed and I'm running Windows 7 RTM with IE8 (8.0.7600).  In fact, my symptoms are worse than described, i.e, when the ActiveX control loads the photo browser window shrinks down to an unuseable size.  Adding the home server site to compatibility mode doesn't work.  This with Power Pack 3 beta installed as well as all HP updates.

My work-around:  Since I'm using Ultimate, I have the option of installing and running Windows XP Mode.  While in the virtual Windows XP, I suppress the installation of IE8 and install IE7.  With that, I can use the activex control.

 I hope this is fixed by the time Windows 7 hits retail shelves.

Addendum (9/19/2009):  It's working on my laptop.  The above-described problem is on an W7 RTM x64 installation.  My laptop is x86, also W7 RTM.   Perhaps an incompatibility with x64?  Who knows.
