when you press alt+tab or put the soldat window in the "background" to chat on msn or something while playing the image pauses and you cant see whats going on while your minimized, so there should be a setup option to keep the DirectInput or whatever "running" while your doing whatever. So you can quickly retalliate in case some guys catch you off guard (should be good for TW players) but keep it a setup option for slower computers.
In case you dont know what im talking about, when you re-enter the soldat window after exiting it you get a "direct input initialized" message, so if it's possible have this directinput running even when your not "playing"
