has to do with processor and old boxes. I am on an older Mac and not yet ready to migrate over. I have Poser 5 and 6 and 7 all legally purchased but getting my computer ready to install new software means new op system and I loathe that kind of upkeep. Since I lost my job 18 months ago!, I have not had the mind set or the money to make the necessary re-configs.
Poser eases that stupid pain but trying to upgrade would prove my undoing just from the sheer mind warping the process would incur.  :(
