Twitchy AniBlocks

The Brig

I tried playing with the aniblocks using a G8F figure...nothing spectacular, just a simple walk to see if my card and computer could handle it. This is using just the included blocks with AniMate 2 on Studio 4.10.0.123, an EVGA 1060 card, and Windows 7 64-bit. All the drivers are current.

Most of the animation goes fine except when I'm using the "forward (1 cycle) G8F" block. The left leg kicks outward a little bit each time it's supposed to come forward. The right leg comes forward and moves back normally, but that left leg keeps acting like the figure stepped in chewing gum or something. Has that happened to anyone before, and has anyone heard of a fix, update, patch, cure, or incantation to make it behave properly?

Or did I accidentally download the "Ministry of Silly Walks" bundle by mistake?
