Leg dropping in animation pose?

Hey there, first post in here. I'm a new builder who is just trying to make simple poses for furniture that I make. I use Avimator. The first pose I made I am having trouble with, a lying animation for a hammock, where my left leg will drop at varying angles. The only movement in the animation is the left foot rocking up and down slightly. I've included pictures:

It is better or worse with different pose scripts/balls. With the worst scenario on a certain script it happens all the time as in incorrec2.jpg. On the best scenario it happens only occasionally as in incorrect1, which eventually corrects to correct.jpg with 1 or more standings and repeat sittings. Sometimes with the best scenario it will hit right on first attempt. This happens in different sims, in dreamland (yes lag) and on a private residential island (what's lag?) In an effort to fix what I thought was the problem, I uploaded the animation again with a longer ease in time, and it "seemed" to help some but could have been my imagination. Priority is 4, it is looped.

Can anyone tell me what is happening here, and if there is a remedy? Thanks...

Have you applied animation to all of the joints? If there is a joint you did not move in the animation tool, that joint will continue to play the default animations in SL.

I am not sure I did all joints, but pretty sure I moved that particular knee joint. I will try that and see if it helps. Thanks..

Update! That was it, apparently I had not moved the shin joint. Thanks a bunch John...

heh heh, people always get my name wrong. Glad that fixed it.

Crap... sorry bout that... I know what it's like to get called everything under the sun and am usually very attentive to spelling. ;^)
