properties vs local variable

[Terence Heaford]

Thanks Peter,

I think this what the data grid does.

I can see how this works having changed to colour of the group as an experiment.

How would I deal with non contiguous selections?

Create an image for each one?

This is starting to sound expensive time wise.

All the best

Terry
