Sudz, I was just trying to add an event to open the curtain in the briefing room. At the mission properties window I put 60 in for the briefing time. I then right clicked at the mission level and selected add event. I named it "curtain test" and have tried several values in the mission time window 0,1,30.... I was thinking that as long as it was less than 60, the curtain would open. I can right click on the event and test it in the editor, with AHview enabled I see the screen jump to the briefing room and then the curtain opens. But when I save the mission exit the editor and start AH2. I then go into the mission sit in the briefing room for a minute with the curtain closed and then go out to the flight. Is there a build step I could be missing?
