Question

select on start button which is on the left hand side at the button corner of the sreen​

Answer 1

Explanation:

When unlocking the taskbar and moving it to the left boarder of the screen, the start button moves to the top left corner and the clock and show desktop botton are on the bottom left. When I now click on the start button on the top left my modern UI opens. So far everything as intended. If I now click again nothing happens, the start button is gone and to go back to the desktop I have to move my mouse to the bottom left or click the desktop tile (or the desktop button in the apps view).
