To prevent these documents from ever appearing on startup, disable the Auto-Save feature in the Files section of the Preferences panel. This prevents you from taking advantage of any Auto-Save features.
Alternatively, you can prevent these documents from appearing on a startup-by-startup basis. There are two ways to prevent these documents from appearing on restart:
Method One
2. At any time after extensions begin loading but before the desktop appears, hold down the Shift key and keep it held down until startup is complete.
Method Two
2. When the Extensions Manager window appears, release the space bar.
3. Choose "View as folders" from the "Selected Set:" popup menu.
4. Scroll down to the Startup Items folder and deselect any AppleWorks document that you do not wish to open on startup.
5. Click Continue.
Your computer finishes starting up normally.
Note: Any item you deselect is moved to the "Startup Items (Disabled)" folder inside the System Folder. You may wish to delete these items to prevent this folder from becoming cluttered. The items that AppleWorks places here are aliases, so they can be deleted without affecting the original document.
