Running on Window Mode

[z_dize]

Hi, I'm having trouble running the game on window mode. I'm able to run it at full screen perfectly at 1920 x 1080. For some odd (Ok, odd for me maybe) reason, it freezes when I try to run it on Window mode. I tried bringing the resolution down but it still freezes.

Is there a "suggested" configuration for this? I'm running it on XP SP3.
