HyperCard: Fixing New Card Problem in Graph Maker Stack (7/92)

If I make a new card in the Graph Maker stack, it becomes non-functional,
with a string of "Can't understand" messages and so forth. What could be
the cause?

The reason is that the background is trapping the openCard message, and a
handler is sending a message to the CARD script, which is not there for new
cards.

The easy workaround is simply to disable the New Card command for this stack, since there should be no reason to make new cards in this stack.
