 115     WoW Bug: For some reason, setting the thumb texture on the scrollbar causes the following scenario:
 116       1. Display the viewer with scrollable text (eg /qh)
 117       2. Display the viewer with smaller text (eg /qh help filter)
 118     The second time the viewer is displayed, the close button doesn't show its normal state.
 119     When you hover over it, the glow appears.  If you press the left button over it, the depressed state appears.
 120     If you drag off of it, then release, the normal state appears, and the button is fine until you repeat 1 & 2.
 121     ]]
 122     viewer.closebutton:SetButtonState("PUSHED")   -- Workaround: there's a wierd quirk that's causing it to not show sometimes...
 123     viewer.closebutton:SetButtonState("NORMAL")   -- Workaround, part 2
