Sorry folks, but my tool is a Mac program, which will only run on (any) PPC Mac, but not on Wintel. As a matter of fact, it is also impossible for me to write a PC version, because it must run with access to the Mac's file system, which is much more complex than the PC. This means that a Mac can keep a PC file without loss of data, but not the other way round - sorry. On the positive side, there is nothing special that PC Poser creators must do with their files - but feel free to recommend my tool to your Mac users to convert your stuff. Mac creators should be nice and use the "Export" feature prior to zipping their stuff - this way both Mac and PC users get the full package without loss.
