    Compared with Ver 6 I don’t find this is a nice program. The green screens are dreadful. Exporting charts to .png means you are printing A4 pages of solid black with thin coloured lines. What happened to the facility for applying numbers on graphs, which was so helpful in Ver 6? It would be nice to be able to customise charts and background colours to something more useable. I do like the way that one can now move between screens though. I will be reinstalling Ver6 on an old laptop for the better graphics.
