[Gimp-user] Viewing Luminosity Masks

[Alan Huntley <huntley alanm gmail com>]

Installed Saul Goode's revision of Pat's Luminosity Mask script and it runs
just fine, but when I click on the visibility of one of the masks in the
Channels window I just get this "gray veil" over my color image? I would
have expected to see a grayscale representation of the mask. For example,
the DDD mask certainly would be obvious! Any ideas?

GIMP 2.8.18 under OS X 10.11.6

Thanks!
