I have the Logitech Cordless Elite Duo, and have the most recent drivers available from the Logitech website. I haven't had many problems with the mouse, though every once in awhile the cursor jumps to the other side of the screen spontaneously. Anyway, I just started playing Battlefield 1942, and if I try to use the scroll wheel to switch weapons, the program goes batty and keeps cycling through the weapons. It usually takes about 20 seconds before I can get it to stop by repeatedly pressing the button. Has anybody encountered this or a similar problem? Any suggestions?
