Thanks for your efforts and detailed answer Simon.
I'm aware of the 'long tail' in any graph that would chart effort vs supported browsers. It's impossible to make a real site work 100% in every version of every browser on every platform on every device.
Anyway, if it can't be fixed (search and edit working on Chrome on Android) I'll find a browser that does work, or I'll just don't make an mistakes while posting ;-)
If you need any testing done or feedback on this site or the next gen, my offer stands. I can do testing on multiple platforms. It would be a nice way to fill the time when my wife is at the meetings :-p
