I've had it do that to me as well on P6, after I've selected CTRL-ALT-Delete and it opens up the window that shows me all my working files, and soon as I see Poser is Not Responding Poser will jump back alive before I select the End Task button. At least one good thing is, the item in question still loads, just 9 our of 10 times it's missing it's textures and sometimes that can be easily dealt with in the Materials room. But I've also had a few times when it completely chokes Poser and I've had many projects destroyed due to that. Would be nice if future Poser releases would auto save your project every so many minutes in a temp working folder that empties out when you open another file that's not in that temp folder.
