Ever have this happen to you? You copy a text frame in InDesign CS2 or CS3, and then paste it into another InDesign document, and the text formatting completely changes on the pasted copy?
The most likely cause of this is a paragraph or character style (or styles) that is applied to text in the source file (perhaps the pesky Basic Paragraph style). If this same style appears in the destination document with different formatting attributes, the pasted text will take on the attributes of the destination document.
The solution? Select the text in the source document, and choose Break Link to Style from the Paragraph Styles panel menu. Next, choose Break Link to Style from the Character Styles panel menu. This will "unapply" the style from the text, but leave the formatting intact. Now you can copy the text frame and paste it into the destination document, and the formatting will survive the trip.
