Any idea how much horsepower is required to run this reliably? I imagine the Java parts of it need some power. Would it work on a 1.6 GHz single-core notebook or netbook? The processors in these have only about 1/3 the processing power of even a modest a dual core desktop (for example). What does it mean when the screen re-paints itself (most noticeable on the green banner on top)? What does it mean when the node connection status turns white momentarily? FWIW - hitting the refresh key disconnects and reconnects to the node Thanks Ken KE2N
