Javascript viewer shows unwanted transparency

Question

Hi I have WMS service created from 2 layers. One is a polygon shading and another from a PNG symbol.

When you view it with the javascript viewer you notice that the symbols are semi-transparent. You see this when the symbols overlap the polygon shading. You can see it here

Note there is no transparency set on the layers in the MXD.
I tried using this layer on ArcGIS online and there is no transparency effect! see here

When I use this layer in my javascript application I do notice the transparency effect. It should not be there.

Any ideas why this is happening or how to fix?
Thanks

PS ArcGIS Server is v. 10.1

Hi

What version of AGS are you running?

Hi

Have you tried:layer.setOpacity(1.0);

Yes it doesn't change anything. I tried 0.2 and it gets very transparent, but 1.0 or anything higher gives the previous result.
The most worrying thing is that when I view the layer using the javascript viewer of ArcGIS Server I see the transparency.
This tells me it is not an error of my application.

Seems strange no one has encountered this before
