I'm pleased, well actually, thrilled to report that contextual menus have returned to my Personal Bookmarks.
After pursuing numerous technical dead ends, I'd given up.
I just clicked my right Mighty Mouse button, and a menu appeared. Oh, happy day! (Remember the
Edwin Hawkins Singers or watch the
Choeur Gospel Celebration.)
Let's hope I'm not tempting fate by posting this report.
