      Description

      This bug was originally submitted with id #4394847.
      The customer still claims it has not been actually fixed.
      Below is the customer's input:

      ===============================================================================

      <...skipped...>

      The problem is that the MenuItem's in the PopupMenu never receive
      events. The problem exists on Linux, and it does not exist on Windows
      2000. I have not tested Windows XP nor Solaris.

      I have been testing on a SuSE 8.0 system, running a 2.4.19 kernel.
      Here is the version information for the SDK:

      java version "1.4.1_01"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
      Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode).

      I have tested on the following window managers/desktops:
      sawfish (for gnome),
      metacity (for gnome2),
      KDE 3.0.5,
      WindowMaker,
      icewm,
      twm,
      fvwm.

      The problem exists for all mentioned window managers/desktops.

      There are many other bugs which I believe are related:

      Thanks for you time and let me know what you find.

      Best,

      I have also verified that bug exists under Linux w/Gnome desktop.
      I did some initial evaluation that I've put into the comments section.
