its not that POser 6 does not like 2GB plus. it's the Windows 32Bit limit of 2GB per program that it's had trouble with. as poser content has grown in size, this has become an issue. SR2 went someway to fix this issue in poser and hopefully in P7 it'll be history.. bascially what is happening (at times - depends on scene etc) when Poser requests more System Ram (psychal RAM + Virtual Ram = System Ram), and it hits the Windows limit, pre SR2 it did'nt know how to handle the resulting error properly. SR2 put code inplace to patch this, but a real fix would / will require a rewriting of posers memory handling routines which at the earlist would be Poser 7. personally, your milage may vary, I've found having my System Ram capped at abou 2.5gb has avoided poser erroring. (thats Psychia.. (how the hell do you spell that??) ram at 1.5gb and Virtual at 1gb)
