Description
To reproduce the problem:
* Run the SymbolTest demo applet on a Windows platform using AppletViewer
* Resize the applet window to be about twice as wide as it originally appears, as if to make the horizontal scrollbar disappear.

After the window has resized, you will see a horizontal scrollbar at the bottom of the scrollpane, even though the scrollpane is wide enough to display all of the content.  Trying to interact with the scollbar with the mouse, you will discover that the scrollbar doesn't actually exist - it is some sort of painting artifact.  Minimizing and restoring the window causes the phantom scrollbar to disappear.

This has been the case since b75, but not w/ b74.  (Note that before b74, you could still see the scrollbar momentarily before it was erased).
