first of all, hopefully, you are doing incremental saves of you pz3 as you work along, so if one gets really messed up you can toss it and go back to the next prior version... To respond directly, you likely have spline interpolation turned on for the frames involved. Making little tiny changes in one spot under this 'mode' is a sure-fire way to create chaos and flying body parts just forward and/or back of the changes. Make a new copy of your master. Go into the animation pallet. Change the frames to 'linear section', or even 'constant section'. This will stablize things. But more important, you may wish to begin working in graphs. There you will SEE the affect of a move on all the frames around the move. ::::: Opera :::::
