ravenfeeder: 4.0.3.126 for my Mac also crashes, probably because the memory leak in Poser4 & 4.0.2 is still a problem. I have 150mb RAM devoted to Poser, but it looks like I'm going to have to invest in another 128mb of RAM if I want to work without too much concern about crashes. Rendering a series of images really does a number on the program. Thankfully, when mine is about to die, rotating a figure begins to slow way down & using parameter dials gets sluggish, so if I'm alert enough I know then it's time to save everthing. Last night I stupidly ignore my own advice & after working an hour on a scene saw it flicker away to nothing. God, how I hate & love Poser!
