cmaglie:
Nick, probably you have the hardware folder populated, there is a bug that crashes the IDE (we introduced it in the last beta, due to the new Boards menu with sub-options). We are working on it.
I guess we need a more frequent release schedule.
Er, yes. What hardware folder? You mean if I have some things like the Attiny in my Arduino default folder (for support of the other chip types) then the Due IDE won't start? I take it that is what you are saying.
I'm not particularly worried as I don't have a Due yet, I was just trying to help out with a programming question. Still, it's good to have stress testing, eh?
