strange small object on desktop

[Craig]

I've just noticed a small blue square in the very top left hand corner of my
desktop. It's a Acer TravelMate 4000 notebook, running XP Professional.
When I click on the little blue square (about four square pixels in size) I
noticed it could be moved around like usual desktop objects. A strange thing
happens.. the square becomes a vertical rectangle about 2mm by 10mm, which
itself has a smaller rectangle in the bottom half that keeps changing colour
(blue, black, white and grey). I can't get it to maximise or do anything
else to try to identify it. I've tried restarts and the usual virus scans,
but it keeps reappearing, tucked away as the little blue square in the top
left hand corner.
Can anyone suggest what this might be?

Try right clicking on it - go to Properties- and post what is has in
"Target".

Hi.. thanks for responding. I've tried right clicking, and the object
doesn't respond. I also notice that it can't be placed into, for example,
other folders on the desktop, or the recycle bin. Very odd.
