What figure is it?  It is possible that the Joint Parameter setup for the BODY has such an 'orientation' that this is the proper Y rotation.  Poser doesn't rotate stuff about the world coordinate system - it rotates them about their joints' coordinate systems - including the figure (BODY).  There are other things that could affect this as well (you'll have to talk to VK for an indepth explanation of how channels can change the coordinate system for rotation/scale/translation).

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
