I have a MBP 15 and just upgraded to Snow Leopard. Since the upgrade, my trackpad does not behave properly. The main thing I have noticed is that when secondary click/tap are enabled, when utilized, they yield the expose`. I am able to use control-click, in the meantime, but I am finding it very frustrating. My wife has the MBP 13 and we just upgraded her, as well, everything works fine.

I have reinstalled 10.5.8 and 10.6 just to start from "scratch," and every time I go to 10.6, trackpad issue. I was looking for firmware reinstallation or a driver...

This does not seem to be a settings issue and I couldn't find an equivalent problem in the forums.

I appreciate your help.
