Animation freaks out

I'm designing an animation in poser 5, and I get random freaky movements in-between keyframes(twisting and bending) , but they always are correct AT the keyframe... help? :/

PS: yea yea, I started my animation at frame 2 with frame 1 the default "T" pose.

Sounds like a spline interpolation issue. This should help.

Already tried breaking the spline, no dice. I fixed it by using the same keyframe pasted multiple times instead of the blank frames, and only one 5 frame block where there aren't keyframes but it's a not so wanted crappy fix and any fixes are stil welcome..

Make sure that open Animation Palette and spread out each part information. Break spline toggles. If you tried breaking spline and then move untouched axis, a new spline keyframe would be generated and you could not break it from the upper level. I can't explain it well in English. Please see it on your eyes.

I have this happen anytime I have the T-pose frame set as a keyframe (which it always starts out as) You can try deleting the keyframe, or just add the T-pose frame later. Bascally, the T-pose should NOT be a keyframe, the frame imediatly after it should be.

Boy, that made a lot of sense.

Thanks a ton everyone!

I made the T pose not a keyframe, and added a few more keyframes - Everything's well now!

Although it was a good news that Tsukasa made it, I could not figure it out.
Can you delete any keyframe at the first frame? I don't think so.
