i have a logitech G7 mouse it works fine in xp and in other games but when i launch blockland when i move the mouse down to join a game or move it down in any way it moves it self to the top of my screen outside the blockland window. i tried deleting config.cs no difference. What is wrong ? Its like if i can move it fast i might get to join game on the screen the it bounces to the top any ideas ?
