Viewport rotation

HI there. Since moving from a test version of 2.8 to 2.82 I have a view port problem.

In my old 2.8 I hit . to rotate around a face/edge/vert, tab back to View mode and the rotation remembers that’s what you want to be centred on. In 2.82 the same applies for Edit mode, but when I tab back to View the rotation centre is the entire object I was editing, not the part of the mesh I had selected.

I can’t find a setting that changes this, and yes I’ve copied my settings file into 2.82.

Does anyone know how to change this back so View continues to rotate around the part of he mesh I had requested to be centred?

Thanks.
