If the original script with the 'wait 0 with messages' does not use fully qualified object references, script execution errors can result. Example: My (admittedly quick!) tests indicate that this isn't entirely accurate... Engine generated messages (e.g. mouseUp) behave differently in this regard to pending messages - and even in that case it requires specific action in script for it to occur. So imagine you have a button on stack "S1" which has a single field on it.
