Some gestures not working
I don't know if it's a setting thing or what, but I've been having some issues with the gestures as well. For the most part they are fine, but switching between the desktop spaces isn't working. I thought I was able to at one point use a swipe to switch between desktop spaces, but I can't anymore.
If I'm in mission control I can, but outside of mission control I cannot change desktop spaces. I can't believe Apple would restrict switching to within mission control only.
I've been having some other adjustment issues with the new OS as well..but those belong in other posts I'm sure.
*EDIT*
So I realized that there are some pretty simple options in the trackpad control panel that affect things severely. For example:
Swipt between pages: if set to 2 fingers, you can browse safari history this way. If you change it to 3 fingers, you can't. It also changes from Scroll to Swipe with the different fingers. I'm guessing that refers to the speed of your movement.
Swipe Between full-screen apps: change this option and you can't switch between desktop spaces anymore.
These little options make some major changes to functionality it would seem.
