Mouse pointer disappears
Recently I've been noticing that the pointer of my mouse disappears from the screen. I know that the mouse is working because when I move it an pass by the dock the items amplify, but I can't see the pointer. I've noticed first in certain websites, but when I clicked the mouse it appeared again. Now I've noticed that it did the same in my desktop for no apparent reason.
My mouse is the Apple Magic mouse, and I'm running Mac OS X 10.6.4.
Does anyone had a similar problem?
Cheers
