Attached is a screenshot from the http://wegraphics.net/blog/ page, which I have compared to helvetica neue. You will notice that the mystery font has a round "o".
Also the x height of the Helvetica letters is constant, whereas the mystery font has variations (notice the "v" between the "o" and the "e" - there are others).
@ Rik, if you press Ctrl + mouse scroll up on the page, (link above) it will magnify in your browser.
Bob.
