From what curious Labs has explained to me... yes. I talked to Mr. Hernadez at curious labs after alot of y customers were emailing me that they couldn't render high res maps on 98 or ME. Basically the way he explained the problem was that 98 and ME were programmically incapable of providing memory in one block at more than 128mb. For most programs this is now problem, most programs don't use that much ram at a time. However, Poser asks for lots of memory and all at one time for the dreaded render. Is there a work around? Other than upgrading to an NT kernel software... not that I know of. Betsy
