Firefox Chops Options Box

Firefox has this real sweet annoying error that is bugging the crap out of me. When I go to Tools>Options the bottom part of the box is cut off, so I can’t get to the buttons to change certain settings. Specifically under downloads I’m trying to tell firefox to open media files in winamp, not in itself, but I can’t get to the dang button that opens up which files do what.

So if no one knows a way to get the options box to be fully exposed does anyone know another way to do the file thing I was talking about? About:config didn’t have anything I could find that would fix this.
