I can verify I'm having the same issue. I have tried completely removing shader forge and re-adding it to unity, and also tried restarting unity, but no luck.
I'm having the same issue where I opened a previous edited shader in shader forge. I tried opening them up again, and the window hangs, and then suddenly the shader got reset down to nothing. I had some stuff that involves messing with cubemaps, gloss/spec, normals, and diffuse.
Ideas
If you close it, and then open it again, does it work?
Does opening shaders from their inspectors work?

Which Unity version are you running? Which OS are you on?
Windows 7, Unity 4.1.5f1
I've upgraded to the most recent version just now (4.2.1f4), and that appears to have fixed the problem. Many thanks!
Cool! Hugobeyer, does 4.2 fix it for you as well?
