lockMessagesset [the] lockMessages to trueOrFalse
The lockMessages property returns or sets whether HyperCard sends certain messages automatically. The messages affected are closeCard, closeBackground, closeStack, openCard, openBackground, openStack, resumeStack, and suspendStack. Setting lockMessages to true is useful when you want to go to a card to retrieve or save information, but you don’t want to stay there. (The handler will run faster with lockMessages set to true.) The default setting is false, meaning that HyperCard does send the messages. HyperCard sets lockMessages to false on idle. Examplesset the lockMessages to true
