   Chaz, without sounding rude, this seems like a very clumsy way to hide a 
   few buttons. Sort of bulldozer effect - cover the bloody thing up and it
   might go away....

   What is wrong with:

   on opencard
      hide bg btn BUTTON_NAME
   end opencard

   accompanied with:

   on closecard
      show bg btn BUTTON_NAME
   end closecard

   Those two handlers, placed in the scripts of every card for which Stephen
   wants the bg btns to disappear will work. Alternatively, if there are more
   cards in that background that need the buttons to disappear, than ones that
   don't, then create a new background without the offending buttons (and
   have two backgrounds in your stack - what a concept, eh?)

   Cheers....
