Usually my system (windows 10 desktop) is extremely reliable and fast. Every once in a while I mis-type something (probably involving a special key such as control or alt) And things go crazy. Certain keys stop working (e.g. backspace). after a little frustration and banging of keys a voice pops up and as best I can tell says "Exiting Meredith". It seems that I have put the system into some special mode involving windows or some software I know nothing about. Signing out an then signing back in always clears up the problem until I mess up typing again. Has anybody else seen this behavior? Does anybody know what it is and how to either permanently stop or remove it.
