If it was the obj files you'd get error messages when loading your figures. M3 is quite system intensive so having him clothes & hair in a scene will really push even the best machine add to that the textures for everything & you're really sailing close to the edge. You didn't give any system details so it's quite possible you're pushing your machine too far with everything you're loading, Win2k & XP seem to be the best versions to use P5 with as far as memory management goes. You might get away with it if you increase your swap file, I've set mine to 4Gb & poser seems happy enough with that. Another thing to think about though is the standard poser5 runtime, it's a good idea to not install anything in there as I've found Poser5 becomes unstable if you overload the runtime. Try seperating items from different sites or characters in their own runtime & link to them instead. One last thing :) seriously consider buying PBooost or P.O.O.P to help manage the folders, don't use explorer unless you're very brave :)
