Apple magic trackpad. Strange behavior

Question

Apple Magic Trackpad

Evening!

He became the owner of a magic trackpad, and he behaves strangely - gestures with 3.4 fingers do not work. You swipe 4 fingers over it - the cursor freezes for 10 seconds. The same thing if 3.
But 2 if you hold your fingers - everything is okay. And one.
Axis - 10.6.7

What could be the reason?

Answer 1

Changing the bluetooth adapter helped.
After replacing it with another glitch disappeared.

Answer 2

I'm fine, the OS is the same.
Maybe you should look at the trackpad's settings (System Preferences -> Trackpad)?
