I've never heard of this Trajectory thing before. It's now called Motion Path. Whats really annoying is once you turn it on it won't turn off and is everywhere until you close max, restart it, and open the file back up. Selecting everything and trying to turn it off in the properties doesn't take and also re-opening the file doesn't either! I had to close max down. But cool to know that option is there. Never seen it before.
