Such good advice - I was convinced my download maps by area was broken, because I assumed the area should be the display area.

As is properly documented, you select the area as the last two points visited, e.g. click to center on the diagonal corners you want, and that's your area. I'm not sure off-hand how this could be clearer without resorting to documentation, as you have...

Good work with 2.0 - sorry for some of the avoidable hassle we users generate, and you should be proud of your creation. I'm looking forward to diving into the codebase some time and supplying patch upgrades...
