<< Hey, Steve... When you use OS9 applications or files under your 10.3.9 OS, maybe your system opens Classic in order to do that? That's what happens to me when I try to open an old file that was made and saved under OS9. Classic opens and then I can work with it just fine, but technically, I'm not working with OSX. I'm on the same machine as my OSX, but Classic is doing all the work. I must say, tho', as I'm up to 10.4.8 now, I rarely go back to use any Classic files or applications anymore... keith whaley >> Keith, It all depends. For example, if I open a ClarisWorks doc that I created in OS9, it will run classic and then open the OS9 version of ClarisWorks (because I have no OSX version of ClarisWorks), but if I create a pic in an OS9 version of GraphicConverter and try to open it in OSX, it boots the OSX version of GraphicConverter and then opens the pic. So, my conclusion is that it has to do with the app and its connection to it, and not a OS9/classic vs OSX relationship. In fact, this was a recent problem for me as I went to open a Quicken file, expecting classic to open the OS9 version of Quicken and open the file, but instead it booted the OSX version of Quicken and immediately made the file inoperable in OS9. It took a while to rectify the situation, but I did it. I boot into classic every day, and until I can migrate some stuff I have without losing some of it, I will be using classic for a long time to come. Now, maybe I misunderstood the original post (which I can't seem to find) but I thought he was saying he couldn't even use the OS9 files in OSX because he transferred them via a flash drive. Did I read it wrong. STeve
