One often needs to copy/paste the text of an error message into
email or a bug report. Yet the text which is put up
by DialogDisplayer.notify() is not selectable. One has to
resort to transcribing the error message with possible typos etc.
Please change the implementation of (I think it is) DialogDisplayer.notify()
so any displayed text is select and Copy'able.
Right-click in the message window opens 'Copy to clipboard' popup menu.
