Hmmm...  So maybe it's on my P7 application install disk then.  Is there a way to extract it without running the installer?

I am pretty sure it's asking for an .obj.  Maybe I used it to make a new figure and had compressed files turned off?  Would that create a new geomtry somewhere?  Maybe I can locate the .obz and point Poser to that when it asks for the .obj...
