I just installed EA3 and additional to comments reported by ChrisMiller about the "Locks' reports, please, add this "weird" issue that occur once you try to run whatever of those reports, the progress bar got stuck like the query is running but it's not true, if you move your mouse pointer over the progress bar you'll see the child query corresponding to "Blocking lock by user" the query predicate is looking for :BLOCKER_ID that doesn't exist? and if you try to run another different report (whatever) you'll see in the progress bar the query executing is the one that was stuck from "Locks" reports, again you see the query with the :BLOCKER_ID in the predicate.
