I think that got solved as I wasn't doing a clone properly. In any  
case, the issue was not one of speed  (but rather, other descriptor  
calcs being affected because of non-local changes).

Can you send me an example of a molecule that is taking a long time?  
It's possible that ring detection might be the culprit here since  
BCUT's perform aromaticity detection.

Also, are you using the descriptor code? Or the descriptor UI?
