I've got a NOOK HD with an AFN microSD card running Jelly Bean 4.2.2. A half visible circular blue icon has appeared in the bottom left corner of the homepage. It appears on top of what ever app I'm using. When any anything occurs such as when K-9 mail is collecting mail it exposes itself completely and gives a description of that activity in a box. A number appears in the middle of the icon to inform of the number of emails. At rest the number normally shows the date as indicated by Calendar Status Pro in the notifications bar. I don't know what put it there but I can't shift it and is annoying me intensely. Unlocking the homescreen it will not let me drag it towards 'X remove' I've looked and looked through settings but I can't get rid of it. Can anyone help me please?
