Here's my official BR. Please note that the bug only appears if the Source and Program monitor are above each other in the same window. So for now I'll keep using CC2014 but simply move the Source and the Program Monitor into their own separate windows. That way my workflow isn't messed up. Thanks for the help everyone!
******BUG******
Concise problem statement: When doing an insert edit from the Source Monitor, the focus changes to the Program Monitor/Timeline if the Program window is underneath the Source Monitor.
Steps to reproduce bug:
1. Place the Source and Program monitors together in the same window.
2. Make sure the General Preferences' "Set focus on the Timeline when performing Insert/Overwrite edits" checkbox is unchecked.
3. Do an insert edit from the Source Monitor
Results: The Program Monitor is brought to the front and the focus is changed to the Timeline
Expected results: The focus should stay on the Source Monitor, as it does in CC2013.
