The popup trigger thing is very bad design. Sun should have done
something like PopupListener/Event.
On X the popup trigger is 'right button *press*' but on windows it is
'right button *release*'. So you have to check isPopupTrigger both
in mousePressed and mouseReleased.

Insets differ between various platforms and window managers. Our
port should be slightly better in detecting insets than the Sun
Solaris JDK. What version of the Linux JDK and what window manager
do you use?

When the window never was mapped (i.e. the peer doesn't exist) java
has no chance to determine the insets because they depend on the window
manager.
