Update Mac menubar

The final solution to allow me to hide/show menu buttons and have the 
Mac menubar update is this:

For people searching the archives with this question, this is a 
menuGroup in the background, that appears on all cards.  What I 
wanted to do was to hide/show menu buttons when changing cards.

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

This did not work.  The Mac menubar did not update from a script, no 
matter what I tried.   I finally settled on the following solution, 
which I am quite happy with:

The real buttons are hidden, and are as follows:

named "Options1" and labeled "Options"
named "Strategies1" and labeled "Strategies"
named "Empty1" with no label # for when there is no button to show

There are other buttons, but they do not change from card to card.

There is a changeling button, with the id of 3636, that is visible.

The scripts are as follows:

in each card:

# put the name of the button you want to show into gButton
on preOpenCard
   global gButton
   put "Options1" into gButton # use the name of the real hidden 
button that you want to show
   updateMenus
end preOpenCard

# use closeCard only for the buttons that can be changed by the user
# for example, if a menu item can be checked or unchecked, and you 
want this to be remembered
# the closeCard handler saves the user changes to the hidden real button
on closeCard
   global gButton
   put btn id 3636 into gButton
end closeCard

# in the script of each button, if a menu item is changed by the user 
and i want that info
# saved, there is a saveData handler that gets called
# for example:

case "Sound Effects"
global soundIsOn
     if char 2 of line 18 of btn "Options" is "c" then
       put "n" into char 2 of line 18 of btn "Options" # uncheck
       put "no" into soundIsOn
     else
       put "c" into char 2 of line 18 of btn "Options" #check
       put empty into soundIsOn
     end if
     saveData # saves user changes to an external stack, since 
standalones cannot save to themselves
     break



in the stack script:

on updateMenus
   global gButton
   set the name of btn id 3636 to the label of btn gButton
   put btn gButton into btn id 3636
   set the script of btn id 3636 to the script of btn gButton
  # copy the custom properties into the changeling button
   get the customKeys of btn gButton
   set the customKeys of btn id 3636 to it
   put it into tit
   repeat for each line x in tit
     get the x of btn gButton
     set the x of btn id 3636 to it
   end repeat
end updateMenus
