Thanks for that ,
That seems to work just fine.
Strange that it doesn’t respell as soon as the Key Signature is entered? I’ve used other (more humble) Notation progs that do this automatically . . .

Dorico doesn’t respell all of the music when you change the key signature because that can be quite a destructive operation, but I think you’re right that it would be useful for it to be an option.
Another way you could have approached this, I think, would be to put in a C# major key signature (which should cause all of the accidentals to disappear) and then use the Write > Transpose dialog to transpose the whole flow into Db major, which would mean transposing up by a diminished 2nd.
