Hi, i got my first ever Macintosh today (Alu iMac, Leopard) i THINK i have a problem with the mouse (wired version) I can't 'right-click'. I've been to System Preferences and set right-click as the Secondary Button. Also, the side-buttons wont work. Both left and right side are set to 'Expose' but when i push them in nothing happens. When i first set the iMac up this morning i tried them and they worked fine with Expose, but 3 hours later they wont work Thanks for the help.
