Active part in Play auto-switches to first part on save. - Dorico 4

When working on an active part other then top part, viewing Full Score in Play, regularly changes to top/first part without any input from me. Happens every time after save or auto save.

Yes, when Dorico saves, it ends up refreshing the Play mode state, and that currently loses the existing track selection. This is something we intend to fix in future.

Thank you Daniel, now I understand what is happening, easy to adjust to. Thanks again for an amazing program.
