thanks Book - I am upstairs on the big computer, but can I ask where is the carousel. Also this device thingmabob has only been on the kindle about 2 weeks.
The icon is called a Smart Home Button, and it lets you navigate all over the Fire. I can't find out how to remove it, and I'm guessing that it isn't meant to be removed. That would cause more trouble than it does now. It looks as though you'll just have to be careful, jj, or cover it with a bit of sticky tape.
