It can, but as yet I've not worked out how to copy it other
than longhand, you can't save or cut and paste!

At the present time the problem has disappeared again, I
think it will come back when the number of active trains
drops down again overnight, so I will have another go then.

The anoying bit is the fact that even though I think I have
all OnError's covered, it does not go out through one,
giving it's own message box.
