Hi Tony
Well, its onwards and upwards while the old brain can still absorb a few things still, I seem to have a vertical learning curve!
So, success at last! Armed with the above snapshots, I could see what should be happening but wasn't. The manual said, but I may have missed the important part, that I should drag the transition onto the join of two clips (words to that effect) but I didn't see anything about expanding the timeline. So, all I was getting was the 'open hand', nothing else, but expanding the timeline 'enabled' the views you show above (or similar). So simple really, but if it didn't say that in the manual then maybe it should have! I'm quite happy to say that I may well have missed it so it would be nice to know if something about expanding the timeline before adding transitions was in the manual.
As I used to write technical manuals many years ago I was expecting to be told what to do in a 'noddy guide' way, because everyone learns at a different pace so the more explanation given, the easier it is for tyros like me!
Thanks again Tony, for your help. Sadly, it may not be the last time I need help though. ;(
