WarCraft3 works fine both with fullscreen and windowed mode usging wine
1.8.rc1.
If i set virtual screen mode, mouse can not move out virtual screen and enter
alt+tab mouse gone(get back game mouse still working).

I want mouse could move in/out virtual desktop just like StarSraft and other
games. Is there anyway to fix this?

PS. i also traced dinput/device.c IDirectInputDevice2WImpl_SetCooperativeLevel,
but it seems the game do not call this funuction.
