Sometimes when opening a file that was saved with the Arduino selected, it will open with it deselected ((except in Hardware Version 1, obviously). This is inconsistent when opening a file first thing after opening the program and opening multiple files from one instance of the program, but seems to favor the Arduino being selected when reopening.
Thanks for identifying this problem! I’m also able to consistently reproduce on my end. We’ll get this fixed ASAP.
We’ll be adding a lot of unit testing over the next month, which should really help to increase the stability and avoid these issues.
We pushed a fix for this issue as part of the latest V0.5.2 update.
Please let me know if you see this issue again.
