A program is running and its covering the WinU desktop. How do I get to the buttons?
You can use the Title Bar Apps Button to do this. The apps button is set up from the Screen Options tab, in the Title Bar Apps Button section. If the Apps Button is available, click it to see a popup list of all the buttons on this desk. You can run programs right from that list. Programs that are already running have their Apps Button menu icon highlighted in color.
