I'm running 0018, and it has been producing this activity ever since I installed it. I run zone alarm and it will pop up an alert when programs on the computer try to access the internet. Zone alarm also has a little icon in the task bar that displays in and out network traffic. It could be something to do with java updates, but the activity comes from the IDE and not the usual java updates. The only reasion I got curious is suddenly my servo scripts no longer control my servos at almost the same time a new IDE has been released. Just wondering if the IDE downloaded something for the new IDE that breaks 0018. I don't remember any disclosure of the IDE downloading on its own from the net.
