Conflicting Popup Menus

Bugzilla bug #132376

Right click on the applet to view the popup menu. If you right click outside the applet window, the browser popup menu should show. If you right click inside the applet, the applet popup menu should show ("Cut", "Copy" and "Paste").

Bug Behavior:
In Netscape 6.x for Macintosh OS 9 or OS X (with the MRJPlugin), both menus show when you right click on the applet. First, the applet popup menu shows (as expected), then when an item is selected or the menu is otherwise cancelled, the browser popup menu shows (no expected). This occurs whether or not the event is consumed by the applet.
This bug does not occur with Internet Explorer 5.1 on OS X, or any any browser on Windows

If you are using a 1-button mouse, use Ctrl-Click instead of right click.
