If you're on a Mac (as suggested by 'finder'): 1)Open up the folder that the Poser application is in. 2)Click-- just once-- on the application icon, to select it. 3)Choose 'get info' from the File menu, or press 'control-i'. 4)There is a drop-down menu in the Information box. Select 'memory' from that. You can also select it from the file menu itsekf if you have heirarchical menus enabled: there will be an arrow to the right of the 'get info' and you'll be able to select 'memory' directly from that. 5) Enter as high an amount of memory as you can afford to allocate to Poser in the boxes, minimum first. If you're not sure how much RAM you have (and you're under OS9.x; not sure how to do this in OSX) look under the Apple menu: About This Computer. It will tell you how much you have, and how much the system needs. If you're running on a low spec system (as I am), it is helpful to reboot the machine if you've been using anything from Microsoft or Photoshop; there may be others where this is a problem. These have 'memory leak' issues-- they gradually eat more RAM the longer they run, and you need to reboot to free the memory they've claimed. It's also good to keep at least 1 GB free on a Mac using Virtual Memory. Not to do so can cause file corruptions-- ack! It's not happened to me, but I've heard of it. Hope that helps!
