This may have been covered before but here goes...

In HyperCard 1.2, why is a openCard message generated *BEFORE* a
newCard message when the user selects "New Card" from the menu?  I
have isolated this by making a stack with only 2 handlers, both at the
stack level:

  on openCard
      answer "openCard message handled"
  end openCard

  on newCard
      answer "newCard message handled"
  end newCard

When I select "New Card" the openCard dialog is displayed, THEN the newCard.
This is a real problem. I have a stack that needs to initialize certain
hidden fields when the card is opened.  If the openCard handler runs first it
finds these fields empty and croaks.  I know I could have the openCard handler
check for an empty field, but that is kind of a kludge.
