hide/show menu buttons

[Shari]

I have a main menubar on each card (background), works perfectly 
except for one thing.

I want to hide/show menu buttons when entering a card.

on preOpenCard
   show btn "Options"
   hide btn "Strategies"
   hide btn "High Scores"
end preOpenCard

This works when editMenus are true and the Windows version of the 
menu updates perfectly.  But when editMenus are off, the Mac menubar 
does not update to reflect the changes.

I've tried lock menus and unlock menus both before and after 
updating.  I've tried moving the hide/show buttons into the openCard 
handler with lock and unlock menus.

The menu will not update until I click on one of the Metacard stacks, 
home, tools, etc., and then click back into my stack.

I do not want to enable/disable.  I want to show/hide.

I've scoured the archives and every help resource I know of.  So far, no luck.

How do I get the Mac menubar to update without clicking outside the 
window?  From within the script?

Anybody?
