I don't know if this is relevant here but, in another thread, I complained Poser 13 kept looking up, it was off working on something using both CPU time and memory but was unresponsive.  I have now found another factor, it only appears to happen when I load a scene created in Poser 12.  If I create the same scene in Poser 13 by adding all the content directly from the library there is no issue. The same is true if I create an entirely new scene in Poser 13. I am not technical enough to know why that is or what might be causing it but there your are.  It could be specific to my system of course.

 

 

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.
