Since upgrading to 'org-plus-contrib-20160530' this morning I am totally
unable to have an 'open-square-bracket', which negates the ability to
write/compose org-links! It shows the 'open-square-bracket' in the
mini-buffer but never in the required place in the text.

How can I get them back please as its completely stopped me writing my
current project?

Thanks
Sharon.
