@Neyjour - Sorry about not getting back to you. For some reason I didn't get a message that a reply had been posted. From reading through the posted messages I'd have to agree with the advice that Gareee has been giving you. The only thing I'd add is to stuff as much RAM as you can afford in your PC since Poser has always been a memory hog. I just got my boxed Mac version today so have only had a bit of time to tinker with it. I haven't had the slow UI problem in general. There have been a couple of instances here P7 has taken several seconds to respond when trying to move the object properties panel.
