Poser has interpolated the movement in the arm in a sinusoidal pattern from frame 11 to 29. How to overcome? Two or three options: 1) Open the Key frame editor and highlight the frames for the arm where it moves up (1-10). On the top-right corner of the key-frame editor, you'll notice four buttons: a wave pattern (the sine function default), a jagged wave, a straight line, and the spline break button. Click the jagged wave button (linear section). This will cause the motion at frame 10 to stop at the value you select. The result is not very human like as the arm will stop abruptly. 2) Try the spline break function on the arm at frame 10. This will basically do the same thing as 1 above. 3) This is harder but gives you a little more control. Notice in the top middle of the key frame editor, there's a big red sine wave. Click it. Make sure the body part in question is highlighted or just select it in the drop down menu on the resulting pop up graphic. What you are seeing is a graphic depiction of the arm movement for that particular axis. Each dial setting has one of these. You'll probably note that the arm movement (bend I assume) is just as you want from frames 1-10. Note however that it continues up in a sinusoidal fashion, then falls to meet the parameter you defined at frame 30. You can create key frames by clicking on the wave line anywhere and moving it up and down as suits your taste. Play with it. Basically, you can manually adjust the up movement of the arm to gradually slow as it hits the top portion of the movement, then adjust the line to maintain arm position throught frames 11-29. Finally, you can gradually bring the arm down by adjusting the wave line in a non-linear fashion. Takes practice, let me tell you. Also you'll notice it creates key frames all over the place. Again, kind of messy, but I believe it gives you better control over the figure. I know this is a little confusing, just gotta try it a couple of times...you'll see what I mean.
