When I am using the Selection tool, I should see a Snap to Object switch and Transparent/Autofill buttons in the right-hand panel, but they don't appear. I'm using version 13.0.1 build 6326.
Wow, that was a fast reply. As I updated this morning I had assumed I was already on the latest version, but now realise that I wasn't. Many thanks for your fast response - problem solved.
