@A Guy: Yeah, obviously it does, most of the time. Yet you might understand I don't want to do this every time!! Because I consider this not a fix (!), but a workaround! Which costs too much time for an issue which shouldn't occur, even if I have my taskbar on top. When Microsoft offers this option, it should make sure, applications can't confuse it! Esp. when I consider this software was/is installed by Sony (and/or MS?) in the manufacturing/shipping process of my laptop!
