I've just bought a Mac Pro 3.1 and installed ML. Everything is ok except this curious behaviour I've noticed after creating additional users. I'm using a brand new wireless mouse that works perfectly except when I log in as one of these other users. Even having the same mouse config (right click and all this) for all users, when I right click under one of these users, it doesn't do anything. If I log in as the main (admin) user, then it works. One of these other users is also admin but still shows the same behaviour, I can't right click. Any idea why?
