glsmac wasn't detecting my SMAX installation and I figured out that it was because it checked for logo.pcx in the root folder and my installation seems to have it (along with a bunch of other PCX files) in a subfolder called "Color Blind Palette". Once I copied it over it was fine. glsmac should therefore check the "Color Blind Palette" folder as a fallback folder for any .pcx files being searched for... or maybe just do it for logo.pcx?
