JSlider on JColorchooser is not properly render or can't be seen completely. JSlider look like some other unknown component. I checked this in vista ultimate & vista home premium.
Step to reproduce:-
1) Run SwingSet2.
2) Select ColorChooser demo.
3) Click on "Background" button. The color chooser dialog is visible.
4) Select "HSB" tab. Observe that JSlider between the color is not seen completly.
I have the screen shot of the same. I tested this in jdk1.6.0 & its update releasee & also in jdk1.7.0 b14 & it is reproducable.
