This could possibly be a bug.
If you create a resource in your Main Context (web) and try to drag it into another Context (lospen) the item does not go.
This happened due to some confusion on my part. I clicked on and expanded my Secondary Context (lospen) and then clicked the Create Resource Button at the top of the Left Nav. I fully expected the New Document to be created in my Secondary Context (lospen). It was not. It was added to the Main Context (web).
I then tried to drag this Document into my Secondary Context. It appeared to go, but then upon refresh, it was back in the Main Context (web).
I LOVE REVOLUTION SO FAR! THANK YOU FOR THE GREAT WORK.
