I took his advice and it then worked.
Same gentleman guided me here so his advice seems sound enough.
He may well be reading this thread !
Probably me, although "guru" is putting it a bit strong. Sorry I can't help with UCCNC issues as I have never used it for real, just had a look at the demo version. I have had graphics card issues myself, although installing the latest graphics driver helped the last time this happened. Glad you found this site - great source of help and sounds as if someone is now guiding you.
