C#.NET with GW6

[John_JCNassur]

Hi there,

I have a problem:

I've created an application using C3PO and some OBJAPI classes.
This has been written in C#.NET.

When I register the application in a GW7 client, it works correctly, but when I register it in a GW6 client (it's what I need) I get an exception with the GroupWiseCommander class. Does anyone know any incompatibility between GroupWiseCommander class and GW6?

Any answer would be appreciated.

Thanks in advance,
John.
