ADDITIONAL OS VERSION INFORMATION :
Windows 2000 / XP

A DESCRIPTION OF THE PROBLEM :
I have created a JPopupMenu with a title component (JPanel containing JLabel and glue) and some JMenuItems.
When I open the JPopupMenu inside the Applet (WNetscapeEmbeddedFrame) everything works fine, but when the JPopupMenu leaves the browser (HeavyWeightPopup), I can not select any JMenuItems any more.
Reason:
Class PopupFactory, inner class HeavyWeightPopup:
if one of the components inside the JPopupMenu is not a JSeparator or a JMenuItem, then the window of the HeavyWeightPopup is set to be focusable.
When I click on one of the JMenuItems, the AppletFrame looses focus and cancels the HeavyWeightPopup (method windowDeactivated in BasicPopupMenuUI / MouseGrabber. The Items are not selectable

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JPopupMenu with a JLabel as first Item and a JMenuItem as second item, open it, making the JPopupMenu leave the browser to become heavyWeight, then click on the JMenuItem: JPopup disappears without firing actionPerformed in JMenuItem
Note: eventDispatched(AWTEvent) in MouseGrabber does not get fired as well.

NOTE: This only happens inside an Applet (IE 6 / Mozilla 1.0). It works fine in an application or in an AppletViewer.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I expect the JMenuItems to fire in LightWeight and HeavyWeight popups, as they did in 1.4
ACTUAL -
Nothing happended

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Any ordinary JPopupMenu with a JLabel as first Item and JMenuItem as second Item will do, as long as the JPopupMenu leaves the Applet.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Create a JMenuItem for the title component that behaves like a JLabel (disabled, No action, not disabled foreground)
