Ok, I have an external runtime folder now, with a bunch of additional stuff in it. I've launched Poser 6 and have looked at every option, preference and button, but don't see how to direct Poser to my external runtime. So I created a shortcut from the external runtime to my Poser 6 program folder. That worked for about a 10th of the stuff in my external runtime. The other 9/10s didn't show up. Too long a path?
