I neither know if following problem is a HyperCard bug nor if it ever
has been discussed in this newsgropup(I'm working with HyperCard 1.2.2).

If you have a card in your stack with has a message handler "on openCard"
I would think that this message will be send always when the card is opened.

Did you ever try to delete another card in the stack so that automatically
the previouse card which has the message handler "on openCard" will be opened.

I tried it and the card which automatically gets opened didn't receive
the "openCard" message.

For example:

Create a card with this message handlers:

on openCard
  answer "now opening this card"
end openCard

on closeCard
  answer "now closing this card"
end closeCard

Now create a second card in this stack.
Then delete this second card.
You will see that you don't get the dialog "now opening this card" on the
screen.

Is it a bug or is my idea about what message HyperCard has to send wrong?
