i did try deleting the object as above. to no avail. i'm assuming that the 
com server created from my python class can be instantiated by several 
processes (or multiple users) and each will have a separate and unique 
instance without having to make "special arrangements" in my python class.

i'm planning to use the python class as an activex component in an asp 
script. i'm trying to make sure each user will be able to create their own 
unique object. i read somewhere that the class attributes need to be 
modified in some way (made private? with get/set methods?) so that these 
don't get shared across several instances of the object created.
