A direct quote from Hypertalk Reference stack (2.0): "If you send a
message directly to Hypercard, you ensure that no other objects will
handle the message."  This includes the Home stack script, no matter
what kind of HyperGatekeeper you've installed in your Home stack.  Not
only could the virus spread to your home stack, it could then spread
to any other stack w/o warning from your "on set" script.

 My thoughts may not be my own, but they're certainly not my employer's.
