No, not running themes. Sometimes the thing goes really ape, as if it is trying to attract attention while no-one is in the room. And when it goes off when I am trying to concentrate on the program I am using it is very annoying. I can stop it by turning down the sound of course,but then have to remember to turn it up again later. Be better if I could isolate the cause and remove it. It is very loud and very annoying.
