Hi Tom,
Yes, if I've been running in an area where Fiber has set the framerate to unlimited and I then exit the flight and exit FSX, Fiber is shut down, and the FSX framerate is left at unlimited. Don't know that there's a way around that (you might try KILL), but I'm more interested in having utilities start with FSX than the shutdown order, so it's not a dealbreaker for me.
Regards,
John Francis
