3rd July 2013: Please note: the latest, updated, version of Dart Throw is here.
I've updated the Dart Throw ICE node to version 0.9b. The new version utilises the new port dirty state features in the SDK to prevent the compound firing when you make changes in the overall tree. I've also added a cancel button and re-wired the evaluation cycle. All in all, this version is more stable and usable. Big thanks to Amaan Akram for help and advice with the code.
Please note that due to limitations in the SDK when you cancel an evaluation in progress, the values in the PPG cannot be reset to their original values. CTRL-Z will restore those values.
