The basic poser files are in user/shared/poser11 etc on the Mac internal disc I have several runtimes on an external disc. When the Library is opened all files on that disc are in alphabetical order; but when I call up the Poser11 runtime, which is on the Mac's internal disc, the files are in random order. I have reported this to Apple under the beta testing scheme - five times to date. As well as this, if you have the mosr recent render window showing you will find that these too are not in alphabetical order. So far I have had no response from Apple. It did not happen in High Sierra or earlier.
