[Zope] Worldpilot record problem with restarting Zope

Hi all, I have a problem with my worldpilot, I found the worldpilot cannot remove any deleted record after the ZOPE is restarted I have setup my worldpilot and zope in my NT4.0 server successfully, and I can create and delete my record successfully as well, but after I restart the ZOPE, all the removed records are back in again. This creating some problems here, (1) It cannot REALLY remove the records, (2) I cannot restart my ZOPE, (3) If the record cannot remove, then the database will become too large... Can anyone help me one that Thank ADG
