Can't Click Quick Measures OK Button

I had the same issue. Quite frustrating. There needs to be a scalable element to the quick measure window or at very least a keyboard shortcut for 'OK'/'Cancel'. The work around that I have used is to relocate my toolbar to the left of the window (right click on toolbar and select settings and follow the prompts to change toolbar location) which then allows for the OK button to be accessed . FYI  I only get this issue when working on my laptop screen. If i have my laptop through a monitor it functions OK.
