Thanks, Brag - F7 must be the shortcut key for a bucket of cold water?? That'll soon get him out his bunk!
I answered #1 myself - if I'd read the radio messages (which I now know how to do! LOL) I'd have discovered I'd to change speed whilst keeping course
So Navigation passed, and one step nearer my licence
That just leaves #3 - anybody??
Thanks again Brag, regards, Gavin.
