Alan, you have my vote for turning that into a sticky/link/legendary post. Crucial information there - thanks.
Thanks! Reading it again now, it is rather good, isn't it? I think I'll have to copy that, flesh it out, fill in the gaps and make an article (and yeah, a sticky post of it too).
Funny that - I just kept the window open and carried on working on other stuff, swapping back to add/expand on points as I thought of them. If I'd planned to work on it, I'd probably still be fighting the intro paragraph. Sound familiar?
