Click target area to readjust columns too small and off to right

Makes it very cumbersome to readjust columns, you have to get your mouse exactly in the 1 spot where the cursor changes to allow column adjustment. Also the target is way off to the right so it makes it seem like the column cannot be adjusted unless you know to carefully go to the right of the 3 dots to wait for the cursor to change. Please see attached photo.

This is a daily grain of sand in our shoes and makes it hard to do basic daily tasks all day every day.
