Hey! I'm using a Acer Aspire M5-481PT-6851 and it has the Elan Touchpad thing. I'm having some issues with it, actually. The only multigesture command i can do on it is three fingers up and it opens Launchpad. Other than that, most of them don't even work, like two finger scrolling or anything. I can't open mission control, nothing.
I don't really know if that's a known issue or not, but i hope it gets fixed or i get support around here. Thanks!
EDIT: I'm using version 3.5, the latest one, on Mavericks (10.9.1)
