The other question, which is on topic, is whether there are any similar glitches moving from OS9 to X. There haven't seemed to be any, from my limited experience going back and forth between Dad's machine running OS X.1.1 and mine running 9.2.1. Files go back and forth just fine.> Nothing updated (newly writen) just patch... Sounds alot like Apple-OS9 is based upon the same principals as OS6-just patched alot. So this is not an uncommon occurance. I think Apple is the first OS to really rewrite it all and present a "finished" OS to the users. I would not be surprised if Microsoft started anew in the next few years to catch their OS back up to OSX es high mark. As to OS9 file compatibility in OSX, I was completely surprised to find that my printers PPD files (in OS9) can be dropped into OSX 10.2.3 and continue to do their job flawlessly. That is compatability. I have seen very little problems with Acrobat5, Photoshop7 and Illustrator10 opening files in OSX that were created in OS9. But I must admit I have not used OSX enough to be very definative. jj
