How restrict display to 1024x768 on larger screens

Hi Kresten,

May be I don't understand well your problem but here is how I would  
imagine a reliable solution:
Stack window: 1024*768
All objects grouped - group locked - size: 1024 768
Then I would set the scroll of the group according to the screen I  
want to display.
On larger screens if needed, you can set a backdrop with the same  
background than the stack and no shadow (decorations as you wish) and  
center the window.

BTW, why do you don't use 9 cards? :-)

Best Regards from Paris,
Eric Chatonet
