sound its a need to update to XP to manage stable more than 256RAM. Some "freaks" say old WIN2000 is better than XP..more stable no spy etc... I think i will buy 256RAM and XP-after that i update on Poser5 with SR3 :-) i hope it comes and fix the P5 problems we all hear about in the forums. Dont now why my post was here i want answer someone tell the problems he had with frozen Poserrender but it was good to hear...regards ST
