[OpenLayers-Users] Large geodesic errors over long distances

Hi,

When I try using the measure tool on my map (google projection) I get *huge*
distance differences when I test it over long distances (draw a line from
Japan to US crossing Africa for instance). With geodesic turned on it says
this is a couple of thousand kilometers, with geodesic turned off it gives
me a more accurate ( 70.000 kilometers).

You can see for yourself in the  measure example @
http://openlayers.org/dev/examples/ 

Any idea what's causing this? Is there a fix?

Thanks & regards
