Yes, I do! Though I have SI installed too. At this point I think I'll start from scratch, with no OBSE and just the vanilla patch - no SI - and then add OOO again and check. What do you think?
Frankly, I have no idea what might be causing it.
As said, I can't even recall it being reported for OOO - and I've played it since 1.31c IIRC. What I do when I start over is I start from scratch (i.e. complete uninstall/delete), install the game, patch it, check, install OOO, check, install core FCOM, check - and go from there.
