Can't create workspaces when using Enterprise CUI?

[sinc]

I have setup a company CUI that seems to work fine when used as the main CUI. It also works fine when used as an Enterprise CUI, except that whenever the user tries to save the current workspace, Autocad crashes hard. This only happens when the CUI file is hooked as an enterprise CUI, and the main CUI is something like custom.cui.

I have discovered that if I add all the partial-loads to the custom.cui, then there are no problems. Everything works. But from what I read here, I shouldn't have to put all the partial loads in both my Enterprise CUI and my Main CUI - having them in just the Enterprise CUI should be sufficient. Is this correct? And if so, any idea why Autocad (Land Desktop) crashes if I don't add all those partials in both places?

To prevent the crash, have the user create the first custom workspace via the CUI editor, not the Workspace toolbar. Once at least one workspace is defined in the Custom.cui, the crashes will go away and the user can use the toolbar to create additional workspaces.
