Hello, I have had this problem for a while now. It sounds funny, but I have this small square light blue dot that appears on the very left top side of my desktop. It doesn't appear when I open my windows, it just shows on my desktop. Whenever I push the "shortcut to close windows" button, it goes away only to return when I maximize a window.

I have just noticed that when I click on it, my windows media player desktop button selects itself.

Is this anything to be worried about?
