I just hope that there are no other classes that misbehave this way... Unfortunately I couldn't get this to work just right now, also not for the minimal example you provided. I will probably look into it when I have more time on my hands. The real problem, however, is a different one: I use the revtex class to submit research papers to the American Physical Society. And I don't think they will be happy with me providing my own package which works around one of the "features" of their own class. So unless we can get them to fix the class, we (or I for that matter) are out of luck. I haven't consider reporting this to them as I thought it would be useless, but of course one could always try... I still think that we should implement a way to handle this situation in org, I'm pretty sure this is not the only class which doesn't conform to the standards out there. Sebastian
