So I'm trying to change the UEFI (like BIOS) settings.  I restart windows with the shift key, get into the UEFI settings screen, but can't switch to any other menu other than the default one.  The keyboard seems to work, I can change the date and time, and get the help menu with F1, and load defaults with F9, save with F10, etc.  Mouse clicks don't seem to register at all.  There's some help text on the bottom right that's overlayed with the "Exit" tab somewhat.  It also looks like something slides off to the right on startup of the UEFI screen.  The help menu says to push left and right arrows to switch tabs, but that doesn't do anything.  Am I missing something here?
