I've been getting the above message when working in Poser lately; it's only been happening the last week or so, and I'm assuming it's some kind of memory problem. But I have 512 megs of RAM on my computer, and the file in question is only about 64 megs (I've worked with much larger files before). I'm using Win2K with an 800 mHz Athlon CPU, 512 megs of PC-133 RAM, and have a 120 GB hard drive. Has anyone had this problem before, and found a way to correct it? Thanks, Guy Hoyle
