JComponent repaint problem

See Attached program for details:


set CLASSPATH for JFC and run as follows:

java STKFrame

Overlap this window with any other window. Close overlapping window or
move it see new PressMe button you might have to do this couple of time
until it is visble.

I am using JDK1.1.5 and JFC 0.7 on Ultra1 and CDE windowmanager.

Also notice that Layout manger is called only 2times. So who is moving
my button "PressMe" or ContentPane.
