3DSprite: On the Mac, at least, running more than one program at a time is an exercise in faith (and, often, frustration!). That's because the OS doesn't do any oversight on RAM allocation (OS-X is supposed to remedy this). On the Mac, each application is supposed to abide by the OS guidelines on RAM allocation and usage and if they don't, you get system error message 11 (usually) and the system crashes. For that reason alone, I almost never run two applications at the same time (except for printing something). Unless you have a really old computer, it doesn't take very long for PhotShop (or Poser) to initialize, so switching back and forth really isn't an issue like it used to be. If you're running NT on a windows machine, then you have true multi-tasking (both applications are REALLY running at the same time) and it might be worth doing, providing you have lots and lots of RAM. Otherwise, I prefer to allocate as much RAM as possible to each application and put up with the switching hassles. -Jim
