It looks like you're new here. If you want to get involved, click one of these buttons!
At the bottom of the v21 launcher window are two buttons that toggle between Metric and Imperial units. One button is darker gray and the other is lighter gray compared to the launcher background color in dark mode. Clicking on either button flips the state of the two. But which one is active? I can't tell which is supposed to look "on".
And what does it do? Online help says it defines the BASEFILE system variable. However, no matter how I change the state of those units buttons—in light or dark mode—I always get the same .dwt for my BASEFILE until I change it manually.
