Brad, Christian;

Thanks, but that forced it back to a "base layer".  I looked at ticket
6678 as Christian suggested, but I'm not sure I followed it exactly.
In my Apache logs, "true" is lowercase for the transparency. Is it
supposed to be uppercase? I doubt it, because all the example apps
seem to work correctly.

I tested on my Mac with a recent nightly build of MapServer "4.99" and
the problem is the same. I must be missing something. I've included
more of my app below in case something jumps out at anybody. (I'm only
on my 2nd day w/ OL, so mistakes are plentiful).

Thanks,
Rich

map.addLayers([countiesLayer,irrigationLayer,podLayer]);
