MORE INFORMATION

All of the programs included with Microsoft Office 97 support a feature called AutoCorrect. AutoCorrect automatically corrects text as you type it, fixing mistakes like accidentally typing two initial capitals, or correcting commonly misspelled words.

For each person who uses the computer, AutoCorrect settings and words are maintained separately in a file called <User name>.acl, where <User name> is the user's profile. This file is stored in the Windows folder on the computer.

If this file becomes corrupted for any reason, you may encounter one or more of the problems described in this article when you start Microsoft Word 97 or Microsoft Outlook 97, or when you attempt to display the AutoCorrect dialog box in any program.

When you rename or delete a <Username>.acl file, a new <Username>.acl file is created when you start Microsoft Word 97 or Microsoft Outlook 97, or when you display the AutoCorrect dialog box in any program.

Note that the file Mso97.acl is a special AutoCorrect file. Do not rename or delete it unless you have completely removed Microsoft Office 97 from the computer.
