Then in that case I’d definitely like to learn more about the problem, because that’s not how things should be behaving. To help me diagnose the problem, please provide me with some specific things:
– A screenshot of your whole desktop just before you make the edit, showing how things are positioned before you change mode or make an edit
– A screenshot of your whole desktop immediately after you change mode or make the edit, showing how things are positioned afterwards
– The project file itself
– A textual description of exactly what you did (e.g. what you selected in what instrument in what bar, what you then did, e.g. change mode or navigate with the arrow keys, etc.)
Then we should be able to dig in and find out what’s going wrong. Unfortunately the nature of these kinds of problems is that they can be extremely sensitive to things like zoom level, window geometry, the precise placement of the score in the window, and so on.
One thing to check: if you habitually use one of the Fit… zoom levels (like Fit page height), then try adjusting that zoom level by 1% so that it’s effectively the same zoom level, but Dorico isn’t trying to keep the page precisely in height at all times. What you will sometimes find when using one of the Fit… zoom levels is that the change in geometry of the score view between Write mode and Engrave mode, caused by the different panels you have open on the left and right of the window, can cause Dorico to have to recalculate the zoom level, and that can cause the view to shift (though it should always keep the selected item in view).
To adjust the zoom level by 1%, type Alt+Z to open the Custom Zoom dialog, hit the up or down arrow once, and then hit Return.
