Windows XP and CFNA

last version of game client works very bad in WinXP. For example, you want to left game. Press Exit and... crossfire.exe is freezed. Yes, you can kill that process by Task Manager, but that simply operation make me a bit angry. Why i play CFNA on WinXP? Because game works more faster, when at Win7. A bit faster, but it's a critical for online FPS, when you have a part of second to shoot your opponent first.
