This one is with scrollbars and scroll arrows in ZQ and ZC listers.

When there are multiple allegro threads, whatever variable that allegro uses to track scroll speed is losing its mind. This is the cause of support ticket 113:

While I had both Grabber, and FontEd open, the listers in ZQuest instantly jumped from the top of the list, to the bottom, or the reverse, when using the arrow buttons.
