are you using hi rez maps? that may be part of the problem- too memory intense.you may want to try and take the textures into an image editing program to try and make them a smaller file size. What chars are you using? Mike and Vicky are really too much of a memory hog to be useful for anything with over 2 or 3 chars... you may want to use a combination of mike vicky(main chars) and the reg poser possette(background secondary chars). When i had my 200 mmx machine 98 mg ram voodoo 2 card with 16 mg ram on board windows 95 os (less than 3 months ago) i was able to render in excess of 30 figures- but i was using only poser and possette not mike or vickie. I also had to make sure i turned off ALL background apps and tsr's.i could run my os and poser ONLY. A render of 30 + chars would take me anywhere from 4 hours to 9 hours in poser, depending on what rez//format the textures were that i was using. Are you sure it's hanging and not just taking a long time to render? how long did you wait before you shut it down? A typical poser render for me takes about 40 mins and up...even now with a 1 gig machine 256 mg ram and a geForce2 card 64 mg ram on board....
