Ooh - I really must get round to upgrading to 7.10
7.10 is a big improvement on 6.n
That's a very well-worth-doing upgrade. I'm expecting the upgrade to 8.10 to be less radical and less urgent.
I upgraded to 7.10 immediately last time, and it was a bit buggy for a week or two afterwards. I'm not rushing this time - I'll try it on one machine and see. For example, Acrobat Reader vanished for about a month, and it took several weeks to be able to use a scanner direct from a graphics program rather than the command line.
