I posted this in the announcements section along with an issue that was fixed for the CSS selecting, but must have gotten missed?
Still having issues trying to select from the end of the line in the Class Names box of the Attributes pane. You can finagle it in there if you really work at it to get it to the edge of the last letter, but we've always been able to just drag from anywhere at the end of the line and would like that ability back as it's much easier to work with.
