Option button menuitem disabling

[J. Landman Gay]

I have some option buttons that enable/disable certain menuitems using 
this syntax:

  set the enabled of menuitem "blah" of me to false

This puts the left-parentheses next to the item, and on OS X it works 
fine. On Windows XP, the menu item is not dimmed, it remains selectable, 
and the left parentheses is showing like this:

   Button
       (MenuItem 1
       (MenuItem 2

Is there a way around it?
