I thought I might need to do this - so I re-ran the EDP 2.2 and used #4: ANV-Slice Modified Just to try one, and then work my way up. It looks like this is still happening, but the scrolling isn't actually a move of my fingers, just a slight rocking motion on the touchpad.
I will try another one to see if it clears things up - but is there a way to tell which one I am using? Such as running uname -a in terminal allows me to see which proc I am using (x86 or x64), but is there a way to see which one it is utilizing?
Edit: interestingly, doing the EDP rebuild did not require me to re-do the wifi fix, at least for now.
