Symptom
A rectangular white space appears on the desktop after Classic starts up.

Note: This may occur if you have checked an AppleShare (AFP) volume to be opened at system startup time in the Chooser, and that volume requires a password. If this applies to you, see the "AppleShare automatic connection issue" section below.
Solution
The white space indicates the presence of a Mac OS 9 dialog box that you cannot access via Classic. This issue may be avoided by updating to Mac OS X 10.2 or later. To resolve the issue in earlier versions:
1. Choose System Preferences from the Apple menu.
2. Choose Startup Disk from the View menu.
3. Select the Mac OS 9 System Folder as the startup System Folder.
4. Restart the computer.
5. Once Mac OS 9 starts up, you should see the dialog box's contents. Take steps to remedy the situation.
6. When the situation is resolved within Mac OS 9, start up from Mac OS X again.
