Brain,

The button listeners are invoked by the GUI thread, so any lengthy
actions performed by them slow down other GUI actions, like
repainting.  You can use:

    SwingUtilities.invokeLater() or SwingUtilities.invokeAndWait()

or

    EventQueue.invokeLater() or EventQueue.invokeAndWait()     // Java
2

from within the event listeners to set up some code to be run on the
main thread.  Hope this helps.
