After many many crashes I can conclude this:
I jave a dual display setup on my Mac Pro 2009: one on a ATI 4870 card, one on the standrad NVIDIA GT 120 card:
On the main display with the ATI card Quicktime movies are not displayed in FotoMagico (You can add them to the timeline and they export OK but you can not preview them);
Dragging FotoMagico to the second display will result in a crash as soon as you add an item to the timeline.
In short: will NOT work on the new Mac Pro 2009 macs!
