Thankyou very much guys. You've been very helpful. On a sidenote for whatever it's worth, the new version of PRO, 4.9.11, (which I've just downloaded and installed, Thanks Deacon) does not let you change filenames in the library. It always says that the file is in use by another application when it's not. I know I can still do it with windows explorer though. I apologize in advance if this is the wrong place to bring that up. I just thought I'd let you guys know.
