Paul, Robin et al - yes, I am back to good 'ole Netscape 3. The deletion of preferences (which I didn't know included all e-mail folders!) happened when I was trying to set up the User Profile Manager - I checked the box that transferred all preferences to the upgrade - then when I was setting up users, the stupid thing kept duplicating users - I was trying to delete the extra ones - a dialog box came up with each one warning that by deleting the user file, all preferences would be lost, and did I really want to delete the user files. Hell, yes, I wanted to get rid of them - I just deleted away. But then it deleted the preferences not only in the upgrade, but in the old version, too. I tried ALL the various suggestions that came my way (thanks, BTW) to see if I could find the files anywhere, but nada. The search was productive, however, in that I did figure out how to open the cache folder - and found out that my dear 16 y.o. son has been entertaining himself while doing "research", and has a good, healthy curiosity about the opposite sex. And I did have an old bookmark folder on the desktop that I had saved months ago, but never upgraded, so at least I have links to a few of my favorite things. Sigh. Cindy
