1. For the first question - this is expected behavior.
2. For the second question - i wasn't able to reproduce the problem. Can you provide more info for the page ?
Is it in some specific workflow or do you have specific permissions for it ? Is the page public ? This response is result from that you don't have permissions to view it or may be some content in the page require more permissions. We will appreciate if you send some more information for this problem.
All the best,
the Telerik team
