Lost vertical scroll on magic mouse
I upgraded to Lion and lost the vertical scroll in my Magic Mouse. I can use two fingers moving horizontally to get to another space, but the vertical scroll does not seem to work on my computer. I also could not find the preference that save information about the mouse. Some of the preferences seem to have changed as well. Any ideas how to reset the preferences for the Magic Mouse?
