I tried doing Edit->Figure->Zero->Zero Figure Pose, but then the pose does get reset though the character moves to a different location. Any easier way to reset without the character moving?
Find a "Zero" pose in either your smart content pane or in your library, wherever you store your poses. Hold CTRL and left-click twice on the zero pose. Uncheck all of the "Translation" checkboxes. That'll likely be the least cumbersome way, at least.
