so i just upgraded to lion and now when i scroll with two fingers my browser randomly changes the zoom level. i have unchecked all of the options for scroll & zoom in system preferences to try to solve it with no avail. i also use magic preferences and do not have any settings set up for trackpad so i don't think that is the issue. any idea how i can resolve this? i am tired of hitting command +/- to get my screen back to the right zoom level.
