Nano War presents an error stating “Unable to Connect to Server” when attempting to play using the latest version of Safari—v3.1.2 (5525.20.1).
No amount of reloading (as suggested by the instructions) eliminates the error. It is reproducible across a number of Macs running 10.5.4 and Safari 3.1.2.
Firefox 3.0.1 does not exhibit the error via the same client machines.
