For no apparent reason, there is a little black box on my screen with a white open, compacted arrow in it and inside the arrow an 'A' (see screenshot). The screenshot shows Mediaplayer open but it is there constantly, independent of which program I am using. It seems 'dead': clicking on it (either right or left) results in nothing. How can I remove it? Now that I have made the screenshot, suddenly there is an arrow through it.
Thanks for advice! IJmir
