I tested my program under Win XP and encountered a problem which I hope u can solve.
There are a few JButtons which are colorized with JButton.setBackground and UIManager.
When Win XP is displayed in Windows-XP-Style (the new and useless Window-look) it overides the setBackground Method/UIManager; but not in the "good old" classic-style.
Especially the backgroundcolor is replaced by the 3D-Button-effect only colored borders are left.
So maybe someone knows how to get around this without losing my beloved buttonbackgroundcolor.
here is some code to try in windows xp.
UIManager.put("Button.background", new Color(157, 0, 0));
UIManager.put("Button.foreground", new Color(255, 255, 255));
jButton2.setBackground(new Color(157, 0, 0));
