Brian/Tim,
Understandable and fine, I will fool around on my next long flight, I'm pretty sure I can overcome the problem. Just put my response down to me being lazy. I have redone a couple of your simulations in Windows but I add extensions and other operational things to suit my particular quirks. I always remove them and destroy them when I get fed up. The last one I did was while I had a three screen set up and had a Windows version of Exeter 90 on the middle screen, Newton Abbot in its present form on the left hand screen and Taunton on the right hand screen. I cheated at Taunton though as I had left the through lines via the goods yard in and had a working connection to the West Somerset Railway allowing their trains in to the station.
It all goes to prove I need to get a life so they tell me. I plan on my next American trip to add some more screens to a Windows version based on Carlisle 1957. Last time I tried I found it to complex but since then I have refined things and it should allow me to enjoy it. The other one half done is the USA Kansas to St Louis line simulation. I have the real layout at Rock Creek Junction and some more details of the St Louis area added. I wanted to include the BNSF at the Kansas end and TRRA in St Louis.
Regards,
Peter
