I learn myself to understand Java and make as exercise in Netbeans 4.0 a
popup program. A start with Frame and add the popupMenu with items. With the
MousePressed I call "poupMenu.show(this, x,y)" and hope to see the popup
menu. But that doesn't happen. The frame window is on the screen but when I
press the mouse I see the next note;

"Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException:
parent is null". It looks like if "this" can not be found.

Thanks for help.
