Problem does appear to be talk designer related. t occurred when using the same figure (M4)  in a different scene.  I then reinstalled the M4 morphs and the issue did not reoccur.  Thanks for the assist.  

P.S. Love the Fog Tool.  One of my favorite Nerd 3D product

Yes. Its an M4 figure. I did determine what the problem was.  I had parented the path to the figure.  When I unparented the path, Walk Designer worked fine.  

Yes, this hasn't changed significantly from Curious Labs' poser 4 through Bonderware's Poser 12.  However, when I attempt to apply "Walk Designer" in an active Poser 13 scene, I can do nothing but 'walk-in-place'.  No follow the path, no transition from starting point.  Just walk in place. 

Thank you for responding.

The problem I run into is that after setting up an animation, I test it out by running the loop. Usually after a couple of loops ( and figuring out heads don't turn that way ;) I toggle the 'stop' button on the animation palette.  Only in Poser 8, the loop continues to run.  I tried pressing ESC, multi-tapping the stop button, cursing myself for not having saved the hour's work, etc.  Eventually I have to go to the Control Panel to 'End Task' the program.  I looked over the enclosed command card and could find no keystroke combination to stop the loop.  Again, I've only encountered this problem with Poser 8 and its only happened a few times so I'm not sure if there's some new feature in Poser 8 that I'm overlooking or inadvertantly activating.

Again, thanks for your response and any help/advice you can provide.
