Once we updated to Swing 1.1 beta 3, we noticed that the background of JScrollBar is not painted under the Windows Look/Feel. All that we can see are the Arrows and the Slider. The area that the slider moves in has the same background color as the rest of the Panel.
This looks really crummy.

If I switch to the Metal Look/Feel the JScrollBar looks quite nice. I hope this will be fixed in the next Swing 1.1 release.

We are running Swing 1.1 beta 3 under JDK 1.1.7a on Windows NT 4.0 Service Pack 3 systems.
