Ken:
Yikes. I should have spotted that permissions error! now many of my layers are
showing up in the legend, which is good. Also looks like I need to generate
these static keymimages for the two raster layers... I thought that those
where auto-generated...
Thanks again for the insightful tips!
Cheers,
Dylan
