Problems when watching two videos at the same time
 

When I watch a video and want to have a short preview to another one, I start this in a second instance. With my XP-Computer this was no problem, but with Win7 the following happens: The second started movie starts on top (in the second monitor), but as soon as I click on the BSP-console for the new movie (in the first monitor) the first movie is active. Then I have to click a few times on both console windows until I have the movie in question on top.

Do I have some settings wrong?
