As others have mentioned, after rebooting, switching does not work anymore until I deselect "Both Shift keys together" and reselect it. Another side effect that might help to nail this bug down is right after reboot, when switching still doesn't work, if I right-click the Keyboard Indicator and choose Show Current Layout, the keyboard layout window that pops up is completely blank, except for the Print and Close buttons. Maybe that will help point out where the disconnect is. Good luck!
