I am using an MS Access 2016 database on an Ultra-HD screen with 282ppi. When I move the input focus to a button using the TAB key, it's very hard to recognize the focused button as the focus rectange is just a 1-pixel dotted line. Perhaps, you'll notice the focus rectangle on the first button 'Name' on the picture below easy on an ordinary 96ppi screen, but it's very hard to see on a high-resolution screen:
Is there a way to increase the thickness of the focus rectangle line in MS Access? Perhaps, you can also suggest another solution how to make an active button more noticeable for the user.
