Ok, we are making progress. I am now using the actual bin directory instead of a virtual directory, and the CuteSoft_Client directory is virtual and pointing to the other client location.

The editor no longer errors out, but it's not working right either.  The first problem is that the custom tool bar I made displays all wrong with big gaps between rows of buttons, and the second problem is that the content does not load!!

Note that when I switch back to using the actual CuteSoft_Client directory instead of the virtual one, the tool bar displays properly and the content loads as it should.

Any ideas?
