Somehow I have changed the TFS 2012 query that is used for code reviews. This query can be found under "My Work" in VS 2012 towards the bottom. I can see the guts of the query by selecting "open query" next to the title "My Code Reviews & Requests" and then selecting "edit query". However, it is not possible to save this query in a way that will change the "My Code Reviews & Requests" or at least I can't see it.
The issue that I have is that someone the query has been changed from the default and I don't know how to get it back to the default. This issue is isolated to me and this specific TFS instance. I can connect to a different TFS instance and see the default query using the same steps as above so I am relatively certain that this issue is related to a specific TFS instance and not my local machine.
