Ok! I installed and tried the "Allow click throughs" right mouse button menu option and now nothing happens on clicking on the clock - the click goes to the app that is directly behind the clock. This clock does not appear under "Force Quit" or app-switcher (alt+tab) or have any active menu items. I uninstalled it, rebooted the machine and reinstalled the clock but still the preference "Allow click through" is persistent. How can I undo the "Allow click throughs" option and bring focus to the clock and get the right mouse button menu? Very frustrating because I cannot move the clock!!
