Hi Peter,

Happy to help. Usually you would allow the overwrite parameter to
default to false. Suppose you create an object with ID foo. Then you
attempt to recreate a new object foo, for example during a recalc.
The system verifies that the new object resides in the same cell as
the existing one, which is the usual case, and the old object is
overwritten by the new one. If the new object resides in a different
cell, this usually indicates an error on the part of the user - you
have tried to create two different objects with the same name - and
the construction of the new object fails with an error message to the
effect that an existing object with the same name resides in a
different cell. If you set overwrite to true then the creation of the
new object will succeed even if the new object resides in a different
cell than the old one. There are not many situations where it is
desirable to set overwrite to true.
I am worried that you have found a memory leak so I am curious to hear
the results of your investigations.
Kind Regards,
Eric
