Ok I figured out what was causing my problem.  If you don't add the
display.getComponent to a frame, it hangs at the wait.  You can see this
in Test50 by just commenting out the jframe.setContentPane line.  I
wasn't doing this because I am writing an application that generates
some images to put on a web page.  I can get around having to actually
display it by not showing the frame. This may be the intended or
required behavior but I thought I'd point it out just in case.


Thanks,
Ben
