While editing, can't copy or cut anything. Paste works as expected.

Update: C-E responded quickly with a work-around. Tbird is the culprit. Thanks.

Sorry, this is a bug in Thunderbird, see

I cannot do anything here.

Only the keyboard command Ctrl+X for cut seems to work.
As a workaround for copy, you can do Ctrl+X followed by Ctrl+V.
