No I didn't take a second monitor. I playing with a wireless saitek gamepad, the mouse and ipad fixed on my legs. It's a very nice mobile solution.
By the way I found two solutions :
1 ) Simple & Elegant : Pressing Windows Key + Right Arrow
2 ) Brutal Force : Editing main.mcf by hand to change the window's rect. If you enter a bad rect (ie out of screen definition) it will be rewrited by the app to default (ie centered window).
