With j2sdk 1.3.1_04-b02 or 1.3.1_02-b02 running with CDE on Solaris 8,
        Solaris 7 or Solaris 9 the PopupMenu class sometime makes a whole Java
        application to hang.

        To reproduce the problem, compile the two .java files in attachment
        and run the MainWindows class:

                % javac MainWindows.java MMainFrame.java
                % java MainWindows

        When the MainWindow shows up, right click on it: a popup menu
        appears with three items. Drag the mouse outside of the popup
        menu but keep it inside of the MainWindow. Right click again
        => the Java application hangs. It does not seem to receive any
        awt events anymore.

        Note 1: The same test-case works find with Java 1.1 and Java 1.2

        Note 2: On Solaris 9 the PopupMenu does not always show up. This
        is also a problem.

Note 3: This problem does not show up on other platforms (AIX,
HP-UX, Windows 2000)

Thanks a lot for your support,
Thierry.
