I have 23 Tabs...

I am unable to add New tab, as when I click on Down Tab, I could only see few tab names and no option of Inserting /Deleting tabs. Mouse Scroll dont work

As soon as I change to Single Screen , IDE works fine, - Even if I move IDE to display 1, tab works fine.

This issue appears in Extended Mode - Second Screen

I am using Windows 10 and Arduino 2 beta 10
