What version of FF are you using? I can't seem to replicate this.
Ok, after much fiddling, it seems the only way you can copy/paste something from another thread, a link from elsewhere on the board, pretty much anything you want to c/p is by using the 'paste' box in the editor bar when posting. This seems a little tedious and extra-time consuming when previously all you had to do was highlight, copy and paste into a reply.
(And thank you for fixing the 'about me' issue!
