Looks good, you should add some hover effects, like just make the text brighter etc
Tested on Windows 7 x64
It works fine for me, 80% of the buttons don't work, I hope that was intended towards the "very limited" part.
I really like the jet black color and basic design.
Until I know the purpose of it, but I don't see the point of the map section, it's nice to have, but it just doesn't seem to mix with the network/general idea of the program.
Windows 7 Ultimate
