Thank you so much for sharing this information- you're a star.
Having gleaned all this I know that you are aware of how tedious it is scouring the web etc to get to the bottom of issues of this nature, and it's something that has been driving me crazy on previous releases and this one. I really appreciate the time you've taken to pull it together and present it so clearly- it's things like this that make this distribution and forum great.
Cheers!
