[OpenLayers-Users] Scale line accuracy

[Steve.Toutant at inspq.qc.ca]

Hi,
The projection of my OL map is in epsg:900913 and displayProjection is 
epsg:4326.
It seems that scaleLine control and measure control do not return good 
values. The scaleline value and the measure are always higher than 
expected.

For the measure control I set geodesic: true and now the results are good. 
But I don't understand why I should specify geodesic: true if my map is 
projected?

For the scaleLine I can't figure out why the scale is not good.

Ideas or extra info on these controls would be appreciated.
thanks,
Steve
