I have a GUI runner class that manages several different windows, one of
which is a JFrame with a JPanel set up as a Grid Layout Manager. My problem
is that when I try to fill the grid with an extended JPanel class, only the first JPanel shows up.
I have confirmed that the others are there but they do not appear.
Everything works fine when I use JButtons or generic JPanels.
I will post code if necessary, but any ideas as to what might cause this?
