I have been looking at it and fiddling with the standalone (non-PassFailJFrame) test to see if I can re-create the behavior without `PassFailJFrame`. I suspected AWT components being the issue but I can't see why.

I tried using EventQueue and SwingUtilities `invokeAndWait()` method to see if either made a difference, but to no success. I tried different layouts for the frame but I got the same result. I'll keep looking but I may also append `windows` to the ProblemList temporarily if I cannot find the source in a reasonable amount of time.
