THE STYLE SHEET IS IN USE BY ANOTHER USER OR PROGRAM. The style sheet you attempted to open or attach is already in use by another network user. ■ Choose File Open again when the style sheet is no longer in use. ■ If more than one user needs access to a style sheet simultaneously, make the style sheet read-only to prevent unauthorized changes to the style sheet. For more information, see Ch. 4 in the Getting Started booklet.
