What causes parts of a figure to be out of place in a walk cycle. 

In this case it is a figure I modeled and rigged.  With Poser walk, run, etc poses the feet are out of place.

When I load the figure .cr2 in "Walk Designer" "Figure Type" the same thing happens.  Feet are like wet noodles when walking or running.

this occurs in Poser 5 and 8.

When I manually set up a walk cycle with key frames and animate, the figure stays together.
