Ohhh! This is too wierd! I had this prob a few months back - asked a friend here and he sent me to this thread: http://www.renderosity.com/messages.ez?Form.ShowMessage=1791044 I followed the number 3. post on this thread and deleting that LibraryPrefs.xml worked like a charm for me...but do back it up before you delete, if that's what you choose to do, just in case. [I put a copy on my desktop, re-started Poser and when I knew Poser was working OK, I deleted the copy.] I said it was wierd, cuz I had the same prob crop again tonight and had to re-fix! Anyway, hope this helps...best regards...
