First of all, it doesn't pass any set messages that DON'T have script in the params, thereby disabling every other use of the set command. Secondly, it gives a false sense of security since any such handler anywhere can be bypassed by a simple statement of the form: send "set whatever to whatever" to HyperCard Using the send ... to HyperCard format bypasses all intermediate handlers.
