Click-dragging in space to right of vertical scroll bar caused window to be moved
Since upgrading to Mac OS X 10.11, I've noticed an annoying issue when I attempt to click-drag the vertical scroll bar up or down but have moved inadvertently to the right of the scroll bar space. The window resizing arrows appear, and, if I click-drag in the space intending to scroll in the window, I wind up just dragging the window instead. This didn't happen before, and it doesn't happen with Windows. I consider this a bug and would like to see fixed. My only workarounds are to move the windows over to the right to hide the offending space from view or not use the scroll bar feature at all. Not at all ideal!
