Cage,

Quote - Apparently they've changed the Walk Designer since I used it, back in the early P5 days.  In earlier versions, I recall being able to paste in pose files and have them show up in the designer.  This no longer seems to be true.

Oh bugger! I hope not. I'm using P6, and can still add new poses. But note that you have to restart Poser, before the WD will read in the new poses. That may be your problem. Please check that and report back.
