Help!

I am new to Warmane, DL it last night and started playing but when i change setting so window mode i get a problem.
I get really bad quality if i leave the game in full res (no window mode) once i change to window mode, i get the window mode, but there is another window of the freezing settings on top of the window mode, meaning to be able to play i need to drag the window mode over to another monitor.

Tried opening the game on the other monitor to get the window mode over to the original monitor by changing main display etc. That just dont work. The game just freezez (image) still hear sounds and can interact, just dont see what i interact with.

Anyone know a solution / have had same problem?

Thanks in advance ( Sry for my English)
