>This is a wild ass guess, since it's not obvious why it wouldn't be rushmore optimized, but have you checked sys(3054,11) to see if it gives you more information?

Yes, something like "using deleted()..." and "Optimization: partial". I just messed a bit too much with the database and won't be able to reinstall it till later in the day. I can be more precise then but the idea is that only the deleted tag is being used.
