UX issue: Left-click drag

Related app/team name (not a must if you want to keep it private): Dota Coach

Issue Description: Left-click draggin from inside an UI element and then moving outside of it, makes all Overwolf UI elements unresponsive. The user has then to click on them first before he can use them again.

Can you reproduce it (exact steps to reproduce): Please look at the video here: https://s3.amazonaws.com/dota-coach.com/Dota-Coch-UX+issue.mp4

Impact for my app: [e.g. x% of the users complained about it, it’s a show-stopper]
Do you currently have a workaround? It impacts probably all users. The user experience is pretty bad, I must say and there is no workaround.
