As it turned out there was a problem with respect to lines who contained only a linefeed (no preceding text) and had a text-align value of "center". For the initiated: it had to do with an incorrect assumption made in the code that a paragraph is not empty if it contains any Knuth element. However, a centered paragraph starts with a glue element and therefore will always have at least one Knuth element even if it only consists of the linefeed (and is therefore empty). > --drkm > Manuel --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
