HypperCard has the obscurely documented message called
"cantUnderstand" that gets send to a card when HyperCard can't
understand a script. Is there more than meets the eye here? Are there
messages for occations when HyperCard can't find a button of a given
ID, etc? Does HyperCard have real error handling?
