When switching to the map view I can still see a line from the shield area and text. It's a single pixel wide all the way down the screen on the bottom of the main view area.
When I switch back there is also a line from the map view. It's grid colored.
It also keeps dots from mining laser blasts.
Edit: I tried it at home and it seems to be an issue only with the work computer. Possibly a screen size issue. I'll have to get the specs tomorrow. I know I use -windowed on a fairly high resolution screen.
Screen resolution 1680 x 1050 and it only happens when I'm using -windowed. Another note is that my start bar is on the other monitor. The extra almost half inch really does help when using AutoCAD.
Is this just a problem with the way it handles it?
