entirely sure how to fix it.

Here is the code I have.  Basically all I want to do is change the
background of the frame to black when I click the mouse (mouseClicked)
and change it back to white when I release the mouse (mouseReleased).
I can't access frame directly to do frame.setBackground(Color.BLACK),

    I would like to change the JSlider's knob color. I saw an  example
on the web that used the BasicSliderUI to do that, but it doesn't work
well. When I use that it paints correctly the Slider but the rest of
