Some letters like the "Q" won't appear in any part of OS X. Any applications or folders that have that letter are missing it. I have already repaired permission, but it hasn't help at all. Picture: -In the Force Quite window it is missing the "q". -In the View Options instead of showing 48 x 48 it shows 4 x 4 , it is not showing the "b" of bottom, and neither the "x" of text appears.
