Ok, thanks - I needed that guidance to know what questions to ask. Feel completely at sea with this. So:
Link widget shows when I select a note
Yes, changes to a curved black arrow when cursor is over it.
When I click and drag, link line does not start drawing.
When I start to drag cursor changes from curved black arrow either to hand tool or normal cursor style arrow head or insert cursor, depending, I think, on very fine distinctions in position of curved black arrow point on widget.
Link creation pop over does not show over target note.
So, can’t click on create link button.
Also, “browse links” option is greyed out in contextual menu.
With links which I created before this problem emerged, I can open link browser in contextual menu. The pop over is missing some formatting but seems functional - I can change the appearance of the link and/or delete it.
I’ve tried it with notes which have only a title and nothing else, and they show the same behaviour as links with titles and text.
Thanks for your attention to this. Appreciate it. I was wondering if I should re-download and re-install?
