Other Cinnamon screensaver doesn't unlock

Hi everyone.

I am experiencing a problem with the screensaver in x11-wm/cinnamon. The problem is that the screensaver will not unlock when I put in my password, instead it says 'Incorrect password'.

Does anyone have the same problem, and hopeful a solution, or is it just me?

Regards Stig

PS - yes it is my own session I am trying to unlock ;-)
