picture a cube that the top vertices in text look like a----b----a. When I highlight "b" and press the hotkey "g" to grab that portion to drag it where i want, it drags the "a"'s as well. How can I grab and move the "b" without moving the "a"s at all? <a href="http://img25.imagevenue.com/img.php?image=60033_question_122_431lo.jpg" target=_blank><img src="http://img25.imagevenue.com/loc431/th_60033_question_122_431lo.jpg" border="0"></a> http://img25.imagevenue.com/img.php?image=60033_question_122_431lo.jpg Screenshot I have nothing highlighted but the dot indicated, no extra lines, dots, etc.
