thumb and 3 fingers !! what a pain this is, and it only works for me at certain times, sometimes not at all, running 4 month old macbook pro, anyone else having problems with my least fav feature?? its driving me nuts !
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.
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.
I have zero issues with this. It works no problem every time I try it using the magic trackpad. In fact, I leave all five fingers on the trackpad at the same time since the software doesn't seem to detect the 5th finger. I also find that you do not have to pinch in all fingers completely together from the spread out finger position to make the gesture work. I pinch my fingers together maybe half way to a "full pinch" position and it works like a charm.
