Horizontal draging the bracket makes MS close.
MS 3.0.1
Way to reproduce:
insert a bracket, any kind of it.
double click it - the square appears to drag it to staff below
drag it (the bracket, not the square) horizontally to left or right
Musescore closes
I don't find it critical by any means, just wanted to report it
Hopefully i'm helping :D
Comments
Brackets can't be dragged (left/right).
But after double-click (edit mode), if you try this (drag), you must click a third time on the bracket, and so you encounter this isssue: #280821: Crash when selecting bracket already in edit mode
So, the good way is to double-click for entering in edit mode, and for avoiding this issue, to grab the handle (and only the handle) for editing.
