@srai: this is almost exactly what happened to me too.
I used it on company PC. It automatically installs itself on private one, too. Never used it to lock private one but all of the sudden it decides to lock it. Company PC unlocks easy but private one does not. Needless to say, if I can unlock one I should be able to unlock the other one. Lost passsword prompt gives the option to set mail to send reset link but after entering it, it says: Something went wrong; and that's it. It stays locked forever.
I guess I'll loose all tabls. Fortunately Opera ties you to your account so it'll at least recover passwords.
