[OpenLayers-Dev] My map will not zoom in past 1: 1066

Are you setting the number of zoom levels on the map or on the google layer? In a recent discussion I was led to believe that OL will pick up settings from the base layer rather than the map...

This may be a red herring, but it's something to try.

Subject: [OpenLayers-Dev] My map will not zoom in past 1: 1066

No matter what I change in my options which are passed into the map constructor I cannot zoom in on my map past a scale of 1:1066.

Here are my options:

var options = {
                projection: new OpenLayers.Projection("EPSG:900913"),
                displayProjection: new OpenLayers.Projection("EPSG:4326"),
                units: "m",
                numZoomLevels: 27,
                maxExtent: new OpenLayers.Bounds(-20037508, -20037508,
                                                 20037508, 20037508.34)

My base map:

                           var google = new OpenLayers.Layer.Google( "Google Maps",
                                                'sphericalMercator': true

I have tried increasing numZoomLevels and adding minScale, minResolution. No effect so I have taken them out.
