Thanks for your ideas. Just to point out people I'm not a newbie to Poser, I have been around since version 3, so I have fair idea of it's workings, Runtime Rodent worked in all versions since it's release back when RDNA was still around, it is only the mentioned update that it hasn't worked with, what I was after is someone to confirm the problem before I took it to Netherworks

I am a bit wary about going to the 3/10 update at least until this issue is resolved one way or another.as it hasn't shown up in Poser as an official update .

The supreme irony of life is that hardly anyone gets out of it alive.
