Well I got this error in Poser 3, got the patch and for the most part it went away or I could work around it by attempting to close the scene and then cancelling the close. Now in Poser 4 the C exception has reared it's ugly head again but I can't get around it. Through indirect means I seem to have found evidence that this occurs if there is something wrong in the geometry of either a prop or of a clothing figure. For example, the P4 bikini caused a C exception for me, so I reworked it by saving the top and bottom as OBJs then reconstructed the bikini using the leotard figure and replacing the appropriate body parts. I would remove each prop one-by-one until I found the culprit then fix it by resaving it as an object then importing it... Krel
