Thanks for the quick reply.
We've got a corporate build, so I cannot update, but I'll report it to the IT powers.
Good to know it looks ok for you.
I have windows 10 and Chromium based browsers have that same thin scroll bar.
I have this same problem on Window 7 and Windows 10, Chrome Version 68.0.3440.106 (Official Build) (64-bit). Any new developments?
