Just recieved my Copperhead this morning, and have already found a problem which is annoying me. I'm currently half-way through Psychonauts, having played so far with my trusty Intellimouse. Using the Copperhead for the first time, it seems that when I'm moving the mouse around to swing the camera, neither the LMB or the RMB work during movement. This isn't just once or twice, I can stand there swinging the camera round and neither button ever works... never had this problem with the Intellimouse. Has anyone ever come across this is any other game / application? Are there any Copperhead and Psychonauts owners who could try this and see if they get the same problem?
