Can not cut/copy text in message field.

Usually obvious when a long winded quick reply results in a log out and invalid thread message. ‘Copying’ text as a safeguard against losing that wannabe post is not an option.
This should probably be considered a feature which persuades people to think and review, rather then typing knee jerk reactions, ill considered queries and poorly thought out instructions [search by author PsychotropicDog and I’ve no doubt you will find some examples of the latter].
My work around of course is to create a new text file.

No right click but Ctrl C, V, and X works for me.

blah blah blah
blah blah blah
oh so it does.

I’d still like the right mouse option
