I use AVG free addition virus checker and no problems with the warsow game installation so far. Of course AVG is FREE so maybe it is just being lazy.
You know that engine sure makes the old engine look kinda sad. Hardly wait till you get WODX weapons installed and get rid of all those sissy lala weaps that are currently littering the maps.
I compared source code for 0.61 and 1.0 and that stuff hasn't changed, so you should still be able to use those keys like before (unless it's some weird bug)
