Tested Platform: winXP-Home/ 2000 Pro (sp4)/ win98-SE
       Browsers: IE6/ NS7.1
       Build: j2sdk1.5.0-b24


Steps to reproduce:

1) Install j2sdk1.5.0-b24 into the test system
2) Using NS7.1 or IE6 to launch the Java2Demo which is bundled with j2sdk1.5.0-b24

 Let's say: C:/j2sdk1.5.0/demo/plugin/jfc/Java2D/Java2Demo.html

The demo should load fine in the broswer. However, if user selects any tab from the top (Colors,Composite/Fonts/Images/Lines/Mix/Paint/Paths/Transform), then that selected tab will become white blank instead of being highlighted. Even the selection tab is turned active but it has a very messy look.
This is a regression. It passed with j2sdk1.4.2-fcs

Furthermore, the same demo should run fine if run using the jar file:
       java -jar C:\j2sdk1.5.0\demo\jfc\Java2D\Java2Demo.jar

It may have to do with repaint problem. Please evaluate.
