I'm using the ECN (vector) charts for the Chesapeake Bay. Everything works fine except for one chart, US5MD18M, which is for Chester River, Kent Narrows and Rock Hall Harbor. Wjen I zoom in the areas just show up as gray boxes. The areas around them are fine. What am I doing wrong?
Well, it's a known bug, so not much more to do then. You can enter the charts and location in Flyspray issue # 506, that would give more points to test when someone gets around to debugging.
