Casamerica, I would consider 4 or 5 installs reasonable and would not want to prevent uou from doing that if needed. Removable media would be treated the same as any other app does. If there's components that are being looked for, you might be asked to insert the disk, or told that the drive is not available. I don't know how this would affect anything except that if I took a Jazz drive to another machine it wouldn't work, unless the OS and Poser app were both on that drive and the machine was booted from it. There's probably a little more to this than I know off the top of my head. The QA guys could probably offer more insight so I'll ask them to clarify. I can think of a few scenarios right now that I personaly don't know the answer to though.
