Actually what I'm seeing is a disappearing island. At a higher zoom  
level I can see Fishers Island, at a lower zoom level it disappears  
(roads, airports, parts, boundaries, everything). When I zoom way  
down (so I can't see anything of CT, only FI, it's still gone). I  
never have on the map grid, so I know nothing of any grid bugs.
