The center button?

[Dylx]

I dont think I ever use the center button on the diamond for anything, Is the a way to remap that button? I would like to remap it to close my programs, I currently have it setup to tap "X" minimize, hold "X" close program. But most of the time in WM6.5 the "X" button is too small to hit, without multiple attempts, could the center button take over that function? Thanks!
