I signed in as a Contributor and edited some content in a document. After finishing it, it disappeared from my list. This made sense because I had it set up as needing approval. I went to another machine as Administrator and approved it. I went to another machine as Reader and now saw the new content. I went back to the machine as Contributor and did not see the new content. All I saw was the document from when I had picked it up to edit it. I did not see the new content until I rebooted the machine. Is this the correct user experience?
