When you select text and then apply formatting to this selection, the formatting may be applied to a larger portion of the document larger than the selected text, or it may even be applied to the whole document. However, if you try to undo the change, only your formatting changes to the original selection are undone.
This issue may occur if Microsoft Word is set to modify a particular style throughout the whole document whenever you apply manual formatting to that style.
To resolve this issue, use one of the following methods, as appropriate to your version of Word.
Microsoft Word 2002 and Microsoft Office Word 2003
Microsoft Word 97 and Microsoft Word 2000
If the Automatically update check box is selected, Word automatically modifies the selected style when you apply manual formatting to any paragraph with this style.
