Hi Myles,
Multi-instance means multiple instance's of the COM server are created
within the same COM Server process. This means standard global variables are
shared between instances.
Single-instance means creating a new process for each instance of the COM
Server. This means there is no sharing of global or any other variables
between instances.
Damn right this stuff can get confusing. Add in-process MTS\COM+ concepts
and it's very easy to make mistakes as I've done many times before.
Thanks,
David.

Looks like it was a good question to ask Nello.
Trying running as "Single Instance" instead. If you define it as
multi-instance, as far as I know, every time you ask for an object, you are
supposed to get a different one. (Can never be sure what COM is going to do
sometimes).

Hi Nello,
I'm running it as Multi-Instance, Single-Threaded.
Thanks,
David.

This may be a really stupid question, but what instancing
option do you specify when you create the COM server?
