 As far as I am concerned, the biggest problem with Poser is its abysmal handling of memory.   The biggest problem with Carrara is its even more abysmal handling of memory  (although the useless terrain editor does provide competition).    Carrara 5 is an even worse memory-hog than Poser, by quite a margin.

Sorry, but your opinion is clearly a minority one. Carrara 5 frequently gets high marks for handling Poser scenes better than Poser. It handles them just fine for me.

It does sound as though you might be having a computer problem yourself.
