Hi Giuseppe,

the OpenLayers.Layer.Vector.RootContainer is created by Openlayers.

Does mq.lqyers() also return the OpenLayers.Layer.Vector.RootContainer?
If that's the case it's a bug.

Generally spoken, you shouldn't care about what layers are created
internally by MapQuery, just use the MapQuery API fo everything and it
will deal with all OpenLayers quirks (that's the point of MapQuery).

Cheers,
