Hi SamT... Yes... you can uncheck 'Smooth but slow user interface' in the main menu! This turns off 'double buffering' of the controls and panes. The smooth interface is fine on a fastish machine, but if you have lower then about 900Mhz CPU speed it's best to switch off the smooth interface. ...if PBooost seems slow, what on earth must Poser be like for you!?!?! LOL! H:))
