The Keyboard menu will appear if any of the following are true:
1. You have selected more than one keyboard layout in your Keyboard control panel (Installed by Mac OS).
2. You have installed an Apple Language Kit (previously sold separately, now included with Mac OS 9).
3. You have installed Multilingual Internet Access (part of Mac OS 8.5).
This is normal anytime you have more than one keyboard layout or script system installed or enabled. You cannot remove this flag and still use the features of the Apple Language Kits or Multilingual Internet Access.
If you have more than one keyboard layout selected, remove the check from all but one keyboard layout. When you close the keyboard control panel, the flag should go away. It is not necessary to restart the computer.
If you do not use any of the additional keyboard layouts or scripts, you can permanently disable the Keyboard menu by removing all of the additional active layouts and scripts from the System suitcase. To do this, locate and open the System suticase in the System Folder. You can then select and move all keyboard layouts and scripts from the suitcase to another folder or the Trash.
