can't use it

BetterTouchTool is a more advanced  version of MultiClutch that I talked about a month ago. It allows to customize the gestures of both Magic Mouse and the multi touch touchpad. It also incorporates functionality similar to “MiddleClick”.

I don’t know why, but after transferring my account from my old Macbook to the new one, 3-finger and 4-finger multi-touch gestures stopped working (in Snow Leopard). To solve this, just reset the PMC. The following procedures is for Macbooks which have internal batteries.

• Shut down your computer normally.
• Press (only once and shortly) left shift + left control + left option keys and the power button.
• Wait 5 seconds
• Turn the computer on. The sleep light should blink shortly.

After doing this the 3- and 4-finger gestures started working again.
