PROBLEM:
If you drag the description tab to the right so its bigger and u can read whats written, the scrollbar doesnt grow with the viewable text. you must hold ur mouse down on the arrow to move the text so u can read whats to the right. if u scroll back to the left to read it again or the next line... u cannot scroll back to the right and must hold the arrow down again. its slow and annoying.
FIX:
Resize the Functions window (make it wider/skinnier), then the scrollbar will get all tiny like it's supposed to be and you can scroll to the right.
this is a tiny bug, not high on the fix me scale lol. just thought i would mention it.
