Hi,
Thanks for the suggestion. I was aware of difference between checked and
'coloured' and had tried the example you suggested. That same example is
in the APIDemos but it in itself has a bug if you rotate at the wrong time,
it gets the highlight mixed up. As I said above, I've mostly got it
working from the SessionsFragment example from the IOSCHED12 Google app.
