I installed the patch. It works fine. Haven't tried all the fixes but it seems stable. Follow the install instructions on the link page. The only thing that seemed a little odd is that after after reboot, the 'prefs' for 600 x 800 (that I use) didn't display all the UI interface utilities. To correct, I deleted the pref file for 600 x 800 that had been created in the last shutdown. Poser created another pref (600 x 800) the next time I ran the app and all is fine - and stable. I would recommend installing it.
