We've used Or for a few years and one thing that makes me very nervous is that the software can update itself after we have tested it, even at an event (we tend to run events internet connected when possible, so that results are live to the web). In the event of a new problem, you are then in deep poop.
I know little about Java, but Googling about the JNLP file syntax, which is used to control the behaviour of Java web-start applications like Or, it does look as though its possible to make web start applications prompt before they upgrade themselves. The default is not to prompt.
Does anyone know enough about this to tell me if I'm right ? (in which case I'll ask Martin to turn it on).
I was looking at
this.
