If you do it the way Fishy suggests, selecting "cut" should work.  Or the "copy" function should also enable you to paste it directly in your comment screen (without going through the extra steps).  Once you highlight the URL try using Ctrl+C to copy it than use Ctrl+V to insert it in the comment box, see if that works.  Or you could simply go "old school" and write it down on a piece of paper and type it in the box along with the rest of your message.
