Hi, Just wanted to let you guys know that Lyx's layout file for revtex4 is out of date (I think). It specifies the package "revtex4.cls" when the current version is "revtex4-1.cls" (as of about a month ago). So right now I don't know how to compile revtex 4.1 documents in lyx. Please let me know if I'm just being stupid and there's an easy fix.
Best, -David
