What are some suggestions for installing 3.x?
As with any software, I recommend disabling extensions before installing (restart and hold down the Shift key) and rebuilding your desktop after installing (use TechTool or restart while holding down the Command and Option keys). I also HIGHLY recommend backing up your Settings, Filters, and Nicknames files before installing. Backing up your mailboxes would not be a bad idea, either. For best results, move your Eudora Settings file AND YOUR PLUG-INS out of your Eudora folder entirely and start with new settings when you first run Eudora 3.x. Move your Plug-ins back in one at a time to insure that they still work with the new version of Eudora.
