Geoserver to ArcGIS question

Hello,

I have added a shapefile featuretype to Geoserver on a local host. I
then add my WMS service to ArcGIS 9.1 and it lists the data in the
table of contents just fine. But I don't see any images at all in the
map window. I've tried zoom to extent, zoom to layer, etc, and
nothing.


Data Type: WMS Service Sub-Layer
WMS Server: http://localhost:8080/geoserver/wms?Service=wms&
Service Name: My GeoServer WMS
WMS Layer Name: topp:county_miv5a

Default Coordinate System:
GCS_WGS_1984
Datum: D_WGS_1984
Prime Meridian: 0

Supported Coordinate System(s):
EPSG:4326         - GCS_WGS_1984


Anyone know why the images won't display in the map window?

Thanks!

Ken
