Cannot make a copy of ENVIRONMENTSHELL

Hi guys,

I'm having a really annoying problem!

I want to make a copy of EnvironmentShell, to use as the starting point for my project, but when I run the copy from the Admin webpage I get the following error:

"Node [xxxxxxxx, xxxxxxxx]: Leaf '' already exists as a child of node xxxxxxxx" where xxxxxxxx can be a number padded out with zeros - the numbers are different depending on your system.

The EnvironmentShell system appears fine, I cannot find these members either in the front end or in RSA1 as InfoObjects, and I optimised each model before running the copy - with no errors.

Any ideas what might be causing this? It's a real problem for me, because until I can do this I can't start building my project environment.

Thanks very much - all help greatly appreciated.

Jason
