Thanks for the info Mike

Still a bit surprised as I'm sure that, on a windows system (I know this is android), one can still enter data in a focused non-visible field (I know you can't focus a hidden control but I thought the focus remained if a focused control was pushed out of sight or something appeared above it). 
I could be wrong!

I'm sending you a poor quality video (issues with file sizes and hand held phone) via WeTransfer.
In it, I'm showing that when I select item 19 I can't scroll at all to see the bottom entries.
However, when editing the setlist, doing the same operation, I can scroll to the bottom - although still limited by the restriction that the selected number has to stay in view.

Apart from the inconsistency in this behaviour, it sounds as though there isn't much you can do about it

Cheers
Geoff
