No, the numbers do not change, they only change when you change the
zoom level.
If you click the link <http://open.mapquest.co.uk/>, you have a scale
of 71 km. If you move the map to the north, the numbers do not change.
If you zoom out and zoom in (pressing - and + on the zoombar to the
right), the scale changes to 210 km, then to 71 km. If you then move to
the equator, the scale stays at 71 km, and again changes to 210 when you
zoom out and 71 when you zoom in.

That, to me, constitutes no change. And it is incorrect.

Coincidentally, the 71 km bar is equal in length to the length of the
north border of Equatorial Guinee. Getting the coordinates from OSM I
get the coast at 9.7755 degrees east and the east border on 11.3434
east. That's 1.5679 degrees, and with 360 degrees around the globe and
40.008 km at the equator (we're talking 2 degrees north here), that
border is just short of 175 km, which is nowhere near the 71 km that the
scale bar would suggest.

Tested on FF 3.6.6 and IE 7 on Windows XP.

Maarten
