Glass Alpha Showing Through Geometry Behind

Hi

When I create a glass material with the refractive colour slot set to light grey so that I can see through it (similar to a glass window) and select Affect All Channels, when it renders the Alpha of the glass show through all the geometry behind it - refer to the attached image of the alpha channel;

I have just upgraded to VRay 2 and this was never an issue before, has anyone else experienced this ?

Thanks

Are you sure you enabled it for refractions, and not accidentally for reflections?

Well, this is embarrassing.

Thanks Vlado, I would appreciate it if you would delete this thread, I feel I have let the human race down !
