Mike and vicky are higher density meshes than posette or dork.. All your memory is in use.. Windows uses memory, if you run anyother programs along with Poser you are using up your memory so adding more than one figure in the scene is really pushing it for poser. Not sure where you are located but Up here in canada the price of RAM is really cheap.. 40 dollars for 256 megs.. if your computer can be upgraded I would definately do that as soon as you can. You'll find Poser and your comp runs a lot better Storm
