256 is quite low on ram for P5. If you're running 98 it's even worse as 98 only allocates 128M per program. Also, as you add more into the runtime things slow up. Try to keep your main P5 Runtime as lean as possible and use either Downloads-- put a separate runtime in there-- or add other runtimes in their separate folders, like one for scifi or fantasy. Sorry to say, but if you want to work with anything but the included content-- if you want to add Vicki3, for instance or any of the Daz figures in multiple scenes, you need around 1G of memory-- I have 2 and it still freezes at times-- XP system and as much processor as you can afford. The program's cheap, the puter upgrade is steep! Emily
