[OpenLayers-Users] layers not transparent

[Richard Greenwood]

I can not seem to make my layers transparent. Only the top most layer
is visible, and it is blocking out the underlying layers. I've tried
transparent:true and format both gif & png. Also tried
isBaseLayer:false.  (example layer below). The layers show up
correctly in the layer control (that is to say they are accompanied by
check boxes as opposed to radio buttons.)

I'm using MapServer 4.8.3 and OL 2.4-rc4 & rc5

Any ideas?
Rich


var podLayer = new OpenLayers.Layer.MapServer.Untiled( "Points of Diversion",
"http://lucca:8080/cgi-bin/mapserv.exe?map=/ms4w/apps/OpenLayers/rwg/wwdc/wwdc.map",
  {layers:'pod', transparent:true, format:'image/png'} );
