Try https://www.posersoftware.com/ and then click the support tab and create a ticket from there, at least that is what I would do. As to whether they want to hear about it I really do not know, they do have a lot on their plate at the moment and I guess it depends on their plans for Poser. At least they should respond to the ticket with information as to whether they are aware, if it is fixed or in consideration for a fix.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
