SOLVED: Can't assign MMB under OSX to middle-click

Can anybody please help? I just got a Mac, and I have a Microsoft Laser Mouse, the Intellipoint software is already installed. I need to set up the wheel button to do a middle click in Blender, but there is no function in the Intellipoint software to do a middle click action. Only “Click”, “Secondary Click”, “Double Click”, and “Triple Click”. So how do I go about getting the middle mouse button working in Blender? Thanks

Edit: I installed USB Overdrive and it allows a middle-click setting, so now it works in Blender!
