HyperCard sends the errorDialog message and its text to the current card if it encounters an error when the lockErrorDialogs property is set true. (In such a case, the ordinary error dialog box is not displayed.) errorMessageText is the contents of the error dialog box that would be displayed if the lockErrorDialogs property were false.
