This may not be a bug, since my set up involves parallels and virtual machines. But I have found that in some windows, the two finger scrolling on my macbook pro is not functioning as expected. If I am in a search window the scrolling is reversed, like I am pushing the page and not scrolling. If I am at the top or bottom of the list it won't scroll either direction.
If I am in a Syntax Graph window it is reversed and it does not scroll left or right.
If I am in a map window scrolling zooms in and out (expected).
Three finger swiping left/right and up/down moves line by line and next/previous resource as expected.
I know supporting VM multitouch behavior is not the norm. But I thought I would put it out there for discussion.
