Hi,
The REVTeX4 layout deals wrongly with the display on the LyX canvas of the PACS numbers (the final output is okay though!). The PACS numbers usually follows after the abstract, and follow the abstract's left-alignment. However, the PACS numbers now align with the main document text and actually are treated as the first section. Consequently, the real first section is indented, whereas it shouldn't, since it's the first. Any idea how to fix this? Also: "PACS number:" should be its plural "PACS numbers:". Regards, Rob.
