[OpenLayers-Users] Layers are not being drawn - proxy issue?

[J. Brian Adams]

I am completely new to openlayers (Started Monday!).  I have been  
working through some examples but with my own data.  I have a map with  
a base layer from openstreetmaps and with a gml layer that I created  
with

			var munis = new OpenLayers.Layer.GML("Municipalities",  
"Municipals2006.gml");
			map.addLayer(munis);

It shows up as Municipalities in the menu on the right, but nothing  
shows on the map.  The gml file is on the same machine, a mac, and in  
the same directory as the html file.  I had read that this might be a  
proxy problem, but at that I am lost.

If this is a proxy issue, how do I work around it?
