dropped internet connection breaks client window

[springmeyer]

If I manually disconnect from the internet on windows (by turning off the airport on my macbook which dropps my windows 7 vm connection), then this breaks the client connection to the tilemill tileserver (but it still works fine in a chrome window).

Logs show:
