If you upgrade to the newer query edit interface but did not allow users full access to search queries, the edit interface displays public queries that the user does not own in the section labeled "Queries I created". Updated upgrading.txt to discuss this problem and link back to the 1.4.17 upgrading instructions. Also included schema.py permissions that can be used to make the edit interface work correctly without allow full search access for queries. Updated the test script in the 1.4.17 upgrading instructions to display protected properties (like creator) to make dignosing this easier.
