I’ve had some problems with this. When I try to select a note head to edit a system or frame it will select the stem,beam, slur, tie but rarely the note head. If I enlarge the page then I can’t see what I’m trying to join together. What I end up doing is selecting the note heads in write mode then going to engrave. Wonder if others have had this problem.
Short answer is ‘yes’… I think there is a plan to improve this.
