Thanks very much for that idea. It has given me much food for thought. I have looked online at what the new format would be and maybe that is the way to go. It does seem sensible not to learn all the functions of v6 at this stage if I need to relearn things in v7.
I am a bit nervous about the upgrade because it seems to be a one-way decision so you have to like it once you have it. I will do some more research on it.
