Charm bars suddenly disappear

Out of nowhere my charm bars will disappear and even the right-click on the windows symbol on the bottom left corner doesn't work anymore. I then have to ctrl+alt+del and sign out then sign in again then things magically go back to normal.
Does/has this happen/happened to you?

Thx in advance!
