--- Comment #8 from Jesse Allen the3dfxdude@gmail.com 2007-12-22 13:48:21 --- Vitaliy, this is a rehash of bug 10839. He wants to run warcraft III (probably using opengl) without changing his wide-screen desktop resolution. The game does not officially support wide-screen and has to set a 4:3 resolution. He can get around this by hacking the registry entry for the game which I suggested to him earlier.
Anyway, wine DOES have to set your desktop to the resolution of the game while in the game. You can't get around this.
