This is copy from a post in the forums i saw weeks ago:

CAn you run the game in a window?

The answer is yes.

You have to edit the registry, though. Change "params" to read:
Quote:
-serverip $QUAD -serverport $PORT -serverotp $OTP -side $SESSIONID -window 1

on the following keys:
HKEY_CURRENT_USER\Software\Playnet\apps\appid1\ins tance1
HKEY_LOCAL_MACHINE\SOFTWARE\Playnet\apps\appid1\in stance1
