On my machine (OpenSuSE 11.1 with Java 6), I get an exception somewhere in
the rendering code:

ERROR [UNEXPECTED ERROR] --> Main$1.uncaughtException [1] Thread:

ERROR [UNEXPECTED ERROR] --> Main$1.uncaughtException [2]
javax.swing.JComponent.paintComponent(JComponent.java:774)

The net effect is that this makes the UI unusable because most of it isn't
rendered at all.
