Brain, Claudio and Ron - In addition to all the other material you guys
contribute to the list, thanks for addressing this with the right folks.
Make sure they understand that it negatively impacts system navigation

Ron, Claudio, and I will all be attending the MVP Conference in Redmond
in about three weeks. We'll be sure to ask the developers then.
Hopefully that's not too long of a wait!
