Thanks for the thoughtful response.
I have spent the last 2 hours crafting a response with screen shots etc but because it took so long I was timed out and my post was lost. It is 3.32am Sunday morning now so I will continue Sunday proper and try to recreate my post that I just lost.
[Note to the MODS: I really do wish that you would extend the time for people to be logged in and 'not be doing anything' because your site doesn't seem to be able to tell when someone is typing, which is really silly. Even a simple script can do that.]
