PowerPoint Slide Show won't allow monitor choice
 

Hello- I just installed Alpha3 and I still cannot choose the desired output monitor for a PowerPoint Slide Show. (This problem started with Mountain Lion) When I try and select another "screen" in set up show (monitor 2 - mini display port out), it will not maintain my choice. If I click "screen" again, it has gone back to monitor 1. If I unplug the USB display adapter, the operation works correctly.

Which version are you using? 2011 works fine for me but 2008 has issues.

Hmmm. I was also using Mac Office 2011. I will try to uninstall and reinstall office. Please let me know if you have any other ideas.

Carlo-
I'm still having the issue after uninstalling and reinstalling the latest version of Office. Are you running 3 monitors as well? I have the iMac as Display 1, a projector as Display 2 via mini-display port, and a confidence monitor as Display 3 via the USB Display adapter (used only by ProPresenter - not PowerPoint). I want the slide show on Display 2 and presenter view on Display 1.
