Would someone be so kind as to explain why the following happens?

I have a fullscreen JFrame.  I have a cheesy render loop (this is the MultiBufferTest code found on Sun's site) that switches colors.

I added a JButton to the content pane of the JFrame.  It works.  Its job is to pop open a dialog box.

The dialog box does NOT open, but!  If i use the following code i can see it:

           mainFrame.getContentPane().paintComponents( g );
//                dialog.paintComponents( g );
                if ( dialog.isVisible() )
                  dialog.paintComponents( g );

Now the funny thing is this - if the dialog is showing, the mouse doesn't do a damn thing over it.  But if you hit the SPACE bar, the actionPerformed() listener method that is attached to the only button in the dialog box (essentially a BIG cancel button) fires.

Why won't the mouse trigger over the dialog box?  I even tried adding a MouseListener to the dialog boxes button... to no avail.

This answer might also help Breakfast out, as he has a similar question.
