When I click Start...All Programs, I get four complete columns of folders
and descriptions. I only see a about half of the folders in the fifth
column, and of course nothing at all of the sixth and succeeding columns (if
there are any). I would expect to get a slider bar at the bottom or maybe
the right when I see All Programs. The end result, of course, is that I
don't have any access to programs beyond the fourth column.

Do I need to tweak something?
