(Popup events are not necessarily right click actions - you should test
all mouse events for isPopupTrigger.)

Is this correct behaviour? If so, how should one add a tooltip to a
frame with a mouselistener on it?

Unfortunately it is the expected broken behaviour for mouse and mouse
motion events. Adding a mouse listener stops the events bubbling up the
component-container hierarchy. Actually setComponentPopupMenu (since
1.5) should be alright as it uses AWTEventListeners.

Some of your choices are:

  o Add the mouse listeners at exactly the same level as other mouse
listeners. You may need to play about with ContainerListener to achieve
this.
  o Add an AWTEventListener. This requires security permissions.
  o Push an EventQueue with an overridden dispatchEvent method. this
doesn't stack well with similar code and prevents system copy & paste
working in sandboxed environments.
