Suppose you have 2 figures in your scene. Under the scene window theres a menu. Pull it down, it'll say Figure 1 or Figure 2. Pick Figure 1. Select 2 and then press 2 on the keyboard or use the menu next to that and select Body. !! Don't click on the figure!! Use the parameter dials to the right of your scene, you might need to scroll the list until you find y trans, y and z. Use these 3 dials to move the character up/down and left/right. Do the same for Figure 2. Obviously some parts will merge, in that case select the figure with the menu under the scene. Then choose a body part (say a leg) in the 2nd menu. Either use the parameter dials or the twist/rotate tools (small icons) above the scene windows to tweak as desired.

Pinky - you left the lens cap of your mind on again.
