UserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36

Steps to reproduce the problem:
1. Click on ARC icon in Apps.
2. Separate tab is opened.
3. Try to take screenshot of the total page by using Snagit (by using scroll down option in snagit) 

What is the expected behavior?

What went wrong?
We are not able to take total page screenshot. But in previous version, ARC was opened in Chrome it self. So we were able to take full screenshot by using Snagit scrolldown.
Now we can take screenshot of Visible page only. I am working as Tester so screen shots plays major role in my job.
Can you help me regarding this.

Thanks
