Implementing ARIS MashZone into PowerPoint Presentation

The same problem occurs when I want to implement the MashBoard as an <iFrame> element in PowerPoint 2010. 

There are several addins on the web that allows to implement HTML pages directly into PowerPoint. Strangely, even real Flash movies (youtube) can be played right within PowerPoint. 

When I implement the <iFrame> element in PowerPoint, and start the slideshow, the login screen appears and I can enter the user credentials. But again, when I hit the login button, the entire screen goes blank. 

Is this a security issue? Aren't we allowed to run the MashBoard in other programs? 

According to this interview with Mr. Klueckmann from 2010, ARIS MashZone can be fully implemented in PowerPoint 2010. But how does it exactly work? Does it work right out of the box, or are additional addins necessary?

I've solved the problem by myself. The blank screen occurs when using IE9 with the newest flash version. After I downgraded to IE7 with the newest flash version, everything works just fine. Even the PowerPoint integration is flawless. charming!  :D

We're currently trying to reproduce the problem. On my machine, with Windows 7, the described behavior does not show up with IE 8 or IE 9.

Still, we're investigating. Do you have some sort of ad blocker, browser toolbar or something similar installed that could block certain JavaScript functions?

Dear Helmut,

The problem occured right after the IE9 installation. I even set the intranet/internet security settings to "low". I haven't used any ad-blocker. JavaScript has been turned on as well.
