I'm dual booting with XP and 7RC1. With XP I use a program called TaskbarShuffle. It allows me to middle click on a program running in the taskbar to close the program. In Win7, middle clicking opens a copy of the same program and TaskbarShuffle doesn't work with Win7 yet. Is there any way to change the middle mouse button's behavior through the registry or does anybody know of another program that will do it? This is the only reason RC1 is not my only operating system. Please help. Thank you.
