Miss B - Thanks for replying to RedPhantom's response. Up through P11, I had to change an entry in the Poser.ini file to trigger the external library. That entry isn't available in the P12.ini; thus I (incorrectly) assumed the external library option was no longer available. I submitted a support ticket when a P12 update hosed up the Poser library, and mentioned the external library option no longer being available. Support's response said they'd fix the library issue (which to date they haven't) but did not mention the external library option is still available.

For P11, I have the external library coordinates plugged into Microsoft Edge, which is the only thing I use that browser for on my graphics computer. Following you advice, I found it works great on P12 as well and eliminated one of my biggest frustrations with the new veesion. Thanks for asking about something I missed.
