NO, one pin of a part should not light up both 12V+, 12V-, and GND.
I wrote it highlights the -12V and the GND, not the +12V is that expected?
I don't know how VAN did that .fzz, because it seams to be a modified original.
If you want to upload VAN's .fzz that you are playing with I can try and see what's wrong.
Sure, the fzz is under his post http://forum.fritzing.org/uploads/default/original/2X/a/a15f83b2e11e91f9c132e7103e6a73daef33ece2.fzz
