I cant reproduce the exact steps to cause this bug ( the worst kind of bug )
but it has occurred three times while trying to demo the very first JTabel
example (chapter 12 - listing 12-1) I am using windows 2000 and JDK 1.3

Exception occurred during event dispatching:
java.awt.IllegalComponentStateException: component must be showing on the screen
to determine its location
