Hi, It's not usually a problem with the .obj file, it's usually with the associated .rsr file, delete that an poser will build a new next time the .obj is used, (you can't do this if the "out of memeory" box is allready on screen though) The thing that really annoys me about this is that once the message appears, once you click "OK" it then deletes the currently active object, (if you have one loaded allready) which isn't good if you've gone a while without saving... later jb
