Windows is generically the same regardless. It's all a swap file/page file/virtual memory, just called different things depending upon which you're using (with NT/2k also having kernel swap). For the most part, right click My Computer, select properties, and look for Performance (or Advanced, and then Performance button, something like that) and you should be able to change it there. If you're on a Mac, couldn't tell you. And if you're getting that as an error message in Poser and you're using Bill (Windows), I forget what it means, but it doesn't mean to increase your page file (unless maybe yours is riduculously small, with the "average" size being your ram + 15 megs for the swap file, i.e., 128 megs of ram would be 143 meg swap file, though this is hardly "correct" or the "only way" to do it). I haven't received that error ages, but I think it pretty much meant close it and start over again (someone wanna correct me on this if I'm wrong?).
