[OpenLayers-Users] change of baselayer changes bbox

[Sven Burbeck]

Hi list,
I have the following problem.
My baselayer is of type "OpenLayers.Layer.Google".  MapProjection =
"EPSG: 3857" (same as 900913).
So far everything works well.
Now I would like to add a second Baselayer of type
"OpenLayers.Layer.WMS".  (Fist I tried using this layer as overlay-layer
and everything worked well)
However, when adding it as baselayer and changing the baselayer by
radiobutton apparently the mapExtent changes and I can't display the new
baselayer (WMS) anymore.

Is there anything, that I have to take into account when adding a layer
as baselayer rather than as overlay?

cheers,
Sven
