Whenever the mouse moves over the marked area, icons are not shaded like they usually are when mouse-overed, and all kinds of clicks (incl band-box, click & drag etc) don't work.
There is a small unclickable area on my desktop, as shown by the following screen grab: also, i've done a search on this topic, and the only relevant result thread is closed, concerning a different version of windows, and has some differences to my experience. Posting in this sub-forum doesn't mean i think it's specifically a hardware problem, whether hardware or software is precisely what i'm hoping to find out.
