I have a bevel panel on a JFrame with some buttons and a
TransparentImage at the top and a tabsetpanel underneath.  The panel
uses GridBagLayout.  On one of the tabs (which also uses gridbaglayout),
I have a grid.  Now here's the weird thing:  when I assign columns to
the grid (either by grid.setColumns() or dataSet.setColumns() and
grid.setDataSet()), the image at the top of my frame disappears!!!!!
(Actually it shrinks down to 1X1 pixel)

What could be going on?  Why are these things related?  And how can I
fix/workaround this problem?!?  Thanks!

The image is being placed on the screen with:

    big_bpanel.add(myImg, new GridBagConstraints2(8, 0, 1, 1, 1.0, 0.0
           ,GridBagConstraints.CENTER, GridBagConstraints.NONE, new
Insets(3, 0, 0, 0), 0, 0));
