The following program shows that resizing this GridLayout does not redraw the Panel/Lists correctly. Actually, if you resize once its draws correctly, resize again, it does not draw correctly (removes the bottom border of the left List), resize again, draws correctly, ..., toggles between correct and incorrect drawing behaviour with each resize.

Here is the layout of the frame:


List 1 List2


Label 1 TextField 1
Label 2 TextField 2

Button1 Button2

GridLayout contains 3 Panels, with the middle Panel containing the 2 Lists.

(In Xerox's application, using GridBagLayout has others issues so they would like to use GridLayout. Further, they say it used to work with JDK1.0.2)
