Thanks for the PM. Nothing is changing very much from the variable world. I recommend you going through all your Rules in the "Rules" tab and de-selecting everything that has a "Log?" checked. This will prevent the "History" tab from getting too large and this might slow things down. You can also check your history tab and see how many items have been cataloged over time. If the number is large, then removing the logging might speed things up a bit.
Actually, there's a variable at the top of the script called "%use_history" that you can change to #FALSE to turn off all history collection. You might try that first instead of unchecking everything to be logged.
If that doesn't work then I'm at a loss.
