A question has been posed to the Mini'app'les MUG and I'd like
to know if anyone else has an answer. What follows is the text of 
the question as it appears in this month's newsletter:

	Hyper Mystery - by Peter Fleck

  The new HyperCard features slicker stack and card designs
  than the old one. An example is the Home Card with its neat
  navigation buttons across the bottom of the card.
  
  I decided to add similar buttons to a stack I was creating and
  began looking for the scripting that controls the hiliting of 
  these buttons as you travel from card to card in the Home stack.
  I used the new debugger, setting a debugging check point in one
  of the button scripts and then using the Step Into command which
  follows the message path to wherever the current handler is 
  running. The navigation buttons only have "go" commands in their
  scripts so I thought there must be an openCard or closeCard
  message handler lurking on some level which would adjust the 
  hilites. What I discovered was that there is no command for 
  setting those hilites!
  
  Who/What sets the hilites for the navigation buttons?

Now I'm curious. I've posted this mystery to several local
BBSs without an answer. Does anyone out in netland have the
answer?

Please E-mail or post.

Thanks,

Tim
