So, I tried to play 2 player skirmish with the other one using the mouse.
The only problem was that the mouse didn't work properly.
It was kinda stuck to the upper screen without showing up even if the lower screen
was the player using it, and when I pulled it all the way down you could see it at the
top of the lower screen. When I goed up again it went "behind" the upper screen.

Anyone having the same issue?
Mouse is Logitech MX518,
OS is Windows 7 Ultimate x64.
