Hi, it seems that my changes are not marked in the output when I use RevTeX but are included when I use, say, the article class. Has anybody experienced the same problem? In http://wiki.lyx.org/Tips/ChangeTrackingLyx1-3-2 it's written than doublespace.sty can cause troubles, but I don't find RevTeX is using this style file. Does somebody have a solution or a suggestion to solve this issue please? - kurt
