BUG - Scroll "nub" not appearing in dropdown boxes

[Omega]

The scroll "nub" (whatever you want to call the moveable part inside a scrollbar) for the map drop down menu does not seem to appear when there's a lot of maps (in my case, 88). As well, using the mouse wheel seems to scroll extremely fast, from the top to the bottom in a single cycle (all 88 maps).
