Well you are using the & event prefix, I couldn't just assume you were.
But yeah, if you or mIRC already used /halt or /haltdef on an event, indeed the next ones won't be triggered if they use the & event prefix, but you must know that or you wouldn't be using that event prefix. The event themselves will be triggered without that event prefix. I now guess you didn't think it would work if mIRC is the one halting (because of the options)
