Files are saved in different locations when using Macintosh Manager 2.2 client and Mac OS 8.1 through Mac OS 9.2.2.
Symptom
It may appear that a document has disappeared if you created and saved it when logged in from a computer using Mac OS 9 and then later logged in from a computer using Mac OS 8 (and visa-versa). No document loss has occurred, but in order to find the document you have to log in from a computer using the same version of Mac OS as the computer you used to create the document.
Solution
Update to Macintosh Manager 2.2.1 or later. It is available from Apple Software Downloads (http://www.apple.com/swupdates/).
