Hi gurus.

I have a problem with a highly customized componet
utilizing MenuBar and SubMenus.

Now I know there is a serious bug that exception
which says "it cannot to be empty in MenuItem" occurs
whenever pressing any arrow kews (left,right,up or down arrow key)
while placing mouse on the menu items.

I have seen at IDE's callstack that shows like bellow:

#0 MenuItem.get-prev ??:??
#1 [{proc} inside MenuManager.process-left-right-arrow-key-press] ??:??
#2 closure_raw_handler ??:??
#3 MenuManager.next-prev-item-in-traversal ??:??
#4 MenuManager.process-left-right-arrow-key-press ??:??
#5 MenuManager.process-key-press ??:??
#6 FocusManagerState.dispatch-key-event ??:??
#7 FocusManagerState.give-event ??:??
#8 View.dispatch-event-to-contents ??:??
#9 GuiManager.fire-event-in-view ??:??
#10 GuiManager.on-key-event ??:??
#11 KeyEvent.fire-methods ??:??
#12 KeyPress.fire-methods ??:??
#13 GuiEventTarget.handle-event ??:??
#14 GuiManager.handle-event ??:??
#15 GuiManager.fire-host-event ??:??
#16 GuiManager.inject-host-event ??:??
#17 View.dispatch-host-event ??:??
#18 [{proc} inside View.window-event-handlers] ??:??
#19 closure_raw_handler ??:??
#20 EventTarget.handle-event ??:??
#21 Window.handle-event ??:??
#22 EventQueue.dispatch-entry ??:??
#23 EventQueue.dispatch-events-aux-aux ??:??
#24 EventQueue.dispatch-events-aux ??:??
#25 EventQueue.dispatch-events ??:??
#26 dispatch-events ??:??
#27 event-loop (?) ??:??
#28 run-applet ??:??

#31 curl-thread-really-really-call-run-in-runnable ??:??
#32 curl-thread-really-call-run-in-runnable ??:??
#33 curl-thread-call-run-in-runnable ??:??
#34 [EMAIL PROTECTED] ??:??
#35 <不明なプロシージャ> ??:??

Quickly I feel MenuManager and MenuItem.get-prev method are important
to understand the problem but cannot find them in online help
although having been looking for them.

Can Anybody tell about them?
Please help.
