Something I noticed while I was testing cross-posting: my LJ is defaulted to friends-only. The cross-post went off without a hitch, and it posted publicly on DL, and to LJ as friends-locked, which is how I have both journals set. When I went back in to edit the post on DW the friends-lock was stripped from my LJ entry. (It went from being f-locked to not-f-locked after editing. I went back in and manually locked it on LJ.)

I'll try again to see if I can duplicate the error.

ETA: Just tried again, and it did the same thing - stripped the friends-lock off my LJ post after editing. I'm using Firefox 3.04, so you know. :)
