[OSM-dev] Projection Openlayers and OSM Data

[Sven Braun]

I have a litte problem with the projection of OSM Data in Openlayers.

In openlayer I got this Coordinates by using mouse over in my MAP: 
877789, 6104757
This would be shown using OpenLayers.Control.MousePosition()

But  the OSM Streets which are shown has the real coordinates something 
like: 877789, 6073033

Does anybody know what is wrong with the Northing coordinate ?
Is this a projection mistake from openlayers ?

Thanks for your help
