I don't know whether this relates to the current Seatle discussion, but for sure I have a problem with the map. I was logging my caches yesterday and pressed the F5 button to refresh my map. I now have a blank screen with only the leftide search screen open. There is nothing more to get. Rest of the site is working fine. If I log out than I do get the map back again. It seems therefore that it is a combination between my login and the site settings.
Working on Google Chrome, but IE has similar behavior.
Any suggestions or solutions ?
