from my perspective, look at the size of a .obj file and then imagine it with all the different morphs and control points activated in a rather large running application. remember that all those presets that you have loaded are also taking up ram as well. poser in my opinion isn't something that can be run on limited systems and acomplish the more intresting tricks. running windows? 240 megs of ram? is that the on board or the ram allocated to the application? my bet is that you've run out of ram.
