A company I was working for had moved ther office, when one of the fire inspectors was touring the edp site, he triggered the halon release for the room, people gasped ands scurried for the exterior, feeling a pressing need for O2... afterwards people could not get their lighters to go out in the programmers offices, I loved it, it only lasted for a while.... what a shame -- ~~ Mike Upmalis (mupmalis@watarts)
