I just got my Pi 2 (BIG YAY!) and was surprised and disappointed that when I went to launch Mathematica or Wolfram, the former starts using 58% of the system's CPU resources to keep putting dialogs up warning about trying to open more than one file at a time (looks like notebook files is what it's referring to), and both apps complained about needing to supply an activation code. It's so insistent that it keeps stealing GUI focus to update the dialogs to the point where I can't type anything into the browser address bar or any other application (updating at least once a second). This is using a Foundation-supplied micro-SD card, so is the current Raspbian download any different?
I need to get this fixed ASAP as I have a lot of important educators and educational administrators evaluating the Pi 2 for wide deployment to every student in the district (12,000+). Will also be posting to Wolfram in case they aren't here continuously.
Thanks, and All the Best,
Jim
