Ed, I've noticed this too, but had assumed I was Doing Something Wrong. So it's reassuring (was going to say 'good', but that's not quite right) that it's not confined to me. In case it helps, I am using IDL 7.1.1 on CentOS.
As another thing which would be nice to change: the Black Sea isn't drawn unless you use /HIRES, and it is a pretty substantial body of water. The Caspian Sea, Aral Sea, and US Great Lakes aren't drawn unless you use /COAST. It would be nice, IMO, to have these all drawn as part of the default map.
