I am using OpenGeo 3.0 and trying to get GeoExplorer to launch through the Layer Preview. I imported PostGIS tables into GeoServer and created a layer. However, when I go to view the layer and select "GeoExplorer-->Go", it opens OpenLayers. Is there something I need to configure?.
I submitted a support ticket w/ OpenGeo and they determined it's a bug and are submitting a bug report. The problem only occurs w/ IE8 on Win 7, at least for me. When I tested on Chrome, everything worked fine. This has apparently been an issue since at least v3.0.2 and still exists in v3.1. I do not know if this is an issue w/ all installations of IE8 on Win 7 or if my workstation configuration contributed something else to prevent the IE8/Win 7 combination from working.
