Michael,
Not sure about the problem your having, will ask around and let you know.
Wozza,
The problem your experincing is a bug in the cfg file, which can be fixed by searching http://www.avsim.net file library for the “bouncing baby dash fix” or some words to that effect.
If you can’t find it, give me a shout and I will send it to you.
Cheers,
Martyn.
