Whoa, I just posted about going back to Poser 4...sounds like it was a good decision on my part. I would have to kill the program when it hung up on loading, 2 or 3 times. Each time it would get a bit further. After using it once, it would start up nicely most subsequent times so I imagine cacheing is already there. K said there might be a further sr after 3? Well, that's nice considering most of the issues everyone mentioned aren't addressed in the proposed 3. I agree with someone elses comment about why do mac and japanese versions while there are still bugs? Ach, what happened to quality workmanship in this country? Make alternate versions with same bugs to just make more money? Shame! Ah well, not my problem, I am out the bucks for 5 but I can use 4....
