Hi, I'm a proud new owner of a 1.5Ghz 15" PB and was playing around with its configurations to get it nice and comfortable to use. I hooked up an MS Wireless IntelliMouse, and the two buttons and scroll button work just fine... but I can't seem to get the two side-buttons to work (the ones that you typically use as a "back" & "forward" function while browsing the net). Is there ANY way to get these two side buttons to work? or will I have to simply go back to manually clicking on "back" and "forward" on the browser window? Any help will be most GREATLY appreciated!
