It looks like it's a larger issue. No matter which screen I'm on, the far lower right button is not selectable. Most buttons highlight when you move the cursor over them.
It's very strange. So far I've seen it in the drive menu (start button), the profile menu (progress button), the build menu (edit button) and the store menu (view cart and checkout buttons). I also just discovered it works fine in windowed mode. And I've done a file verification. Video driver?
