Screenshot with tiny window in upper right corner

With two or more open files in Powerpoint 2007 it is not possible to switch
them via Alt+Tab or the application switch in the Panel.

What happens: a very tiny bit of a window appers and that should be the window
I guess, but the window itself stays empty. (see Screenshot)

Expected Result: Powerpoint should show the other open file.

Workaround: Use the build-in Funktion of powerpoint to switch the window.
