the majority of the lockup's fereezes and out of memory errors are a result of either a missing or corrupt obj/rsr file.. as an example... you download a really neat figure... it's based on the eve V3 figure, but you don't have the eve V3 obj.. the figure will start to load then fail with Poser saying it can't find th eobj.. usually a few times.. then from that point onwards you get an out of memory error... think of it as POser's version of the BSOD.. unfortunately about the only way to avoid them is to ensure you have the obj files that you need. usually verified by looking at the cr2 file. I think a search of the archives for the keyword "Memory" would pull up most of the threads relating to this... good luck
