hmmm. I don't have Poser ProPack so I can't test it in that version specifically. We haven't received any issues or complaints from the people using this stuff with ProPack. ProPack uses a different version of Python, however the GUI interface (Tk/Tcl) is the same version as Poser 5 and Poser 6. All anomalies during developement have been due to the GUI and I test the code outside of Poser in Python 1.52 which is what is shipped in Poser ProPack to ensure Python syntax compatability. So I doubt it is a ProPack issue. Also, nobody who tested this stuff using ProPack reported any problems. Does the P3dO 1.65 have the PoserPython Plug-In or are you using the 'Send To' method? I doubt it is a P3dO issue. External applications (in this case P3dO) are almost completely isolated (de-coupled) from Poser. The issue you experienced may be a sequence of events that uncovered a bug in my code or a situation I haven't anticipated. Let me know if it happens again and/or have any other ideas. thanks.
