use fernando's macConverter lite (or full version), if the file doesn't work without conversion. this was a problem in P4/OS 9, when a substantial part of the PC file was contained in a rsr section, but that may no longer be the case with newer PC files, where only the png section may cause problems. aiko3 also works o.k. in poser 5, OS X. but then, so do all the other figures AFAIK.
