@Roxas,
Yes, Window Mode will be available in the next update (which I should be pushing out to the public servers later today). I'll send you an e-mail when it is published.
To Turn Window Mode ON
1. Before starting World of OMEN, in your World of OMEN installation directory, edit the file "options.ini" in the folder "local"
2. Edit or Add the following line and save the file:
Now when you start World of OMEN, it should start in Window Mode by default. If you want World of OMEN to start in Non-Window Mode instead, change the 1 to a 0. Please note that switching back and forth between Window and Non-Window Mode requires a game restart, so you can't switch back and forth in-game.
This update will be available shortly, I'll post here when it is available through OMENUpdate
