Although tat wasn't the question, here you go: Because it wasn't written to do so, and becuase even if it were, windows would not allow it to do so. Complex operations involved in performing the tasks to which Poser (and most other digital arts applications) are applied are quite RAM intensive at times, and Will be used according tot he most efficient method possible without interfering with other applications. RAM is used first. THe moment RAM is "full", windows, rather than simply telling you "no, you can't do that", shunts chunks of information in RAM to the hard drive in a set location that it is familiar with (and which you can set the size and location of) that is called the "page file" or "swap file". If there is not enough room in BOTH the RAM and the pagefile, then you get the message out of memory. When this happens, the reasonable person will adjust their swapfile up beyond the point of their RAM, so that there is enough space to dump what ever process happens to be running at that time into it (in other words, enough space to store the entire uncompressed file that's already in RAM). Which is what was done. Virtual memory (the pagefile/swapfile) makes a huge difference, as it acts as, literally, extra RAM. If his system had RAM of 8GB, then it's possible he wouldn't have needed much of that swapfile. But since a poser scene can gets quite large (124 jpg tetures, 13 V3's, poser itself, 24 materials, dozens of props) it sorta happens that it will fill ram quite fast.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
