Thanks Robin, I finally got it worked out. Dabo noticed previously on 
Windows that in order to change the Caption of a menu item, we first had 
to SetText("") or the new Caption wouldn't display correctly, so only on 
Windows were we running SetText("") before calling 
SetText(real_caption). So I changed it to SetText(" ") which works 
without trouble.

I'm sure noone else ever calls SetText() on menu items once created 
(they probably just create new menu items and delete the old), so we 
were the only ones that noticed it.
