Hi all. Thanks for the kind words on the vid(s) - As already mentioned there are pdfs in my sig that index the subjects a little better.
As for my absence from the forums - I'm still here but as many of you probably know my other love is riding bikes as fast as I can round various UK race tracks. About a month a go I had a small relatively slow speed unplanned dismount (i.e. crashed

) and unfortunately a crash there is rather more painful and even more inconvenient than when Sonar crashes.
I'm perfectly okay (almost) but did manage to knock myself out, break some ribs, and crock my dominant hand's index finger. Even worse from my point of view I seriously wrecked my track bike (the one in my avatar) so I'm sulking

.
I'm mending pretty well but the crocked finger makes typing slow and frustrating, playing guitar and keyboards difficult and even operating software isn't quite as natural as it should be, so I'm lurking a bit more rather than posting.
I'm sure once the finger is fully functional I'll be back posting more - and hopefully back on the track before winter arrives

.
Thanks again.
