Hi. Yeah, this is something I’ve learned to live with. That it works that way can be useful, actually, at times when the otherwise unwanted jump takes you back to just where you really want to be, which is where you last left the active cursor, the place you were in mid-edit.
I’m experiencing this a lot right now as I’m working with a long scrivening, and occasionally needing to hide and unhide the binder or resize or dock the Scrivener window to half the screen, which reflows not only the text but also the editor’s scroll position in the scrivening… which (come to think of it) is something else I’ve had to learn to live with (or is that the same thing?)
Anytime the editor is resized (e.g., opening and closing the inspector), the scroll position shifts and the cursor can end up off screen. But that annoying behavior can at times serve as a savior in the context of other annoying behaviors. 
@Vincent_Vincent Vincent, is this the post you were thinking of?
