@ Pruiz:

I see you're using my freebie Canvas chair. I made this in Poser 7, even with multiple simulations. But I did that before SR1 came out and I didn't had the problems you described. I don't know if you're using a MAC because the chair was made on a PC, and perhaps I should have let it tested by somemone with a MAC.
 I had some simular problems in the past with simulations in Poser6, (not with the chair but with dynamic cloths) One of the things that can cause those problems is too little memory ; both RAM and virtual memory. Make sure that you have at least 2gig of RAM memory and at least four times that amount of vitual memory. And you need to have enough harddiskspace for the temp files for the simulations.

Hope this helps, but if this is caused by SR1  I would have no answer.

Regards,

Bopperthijs
