I left the project at work. I'll get back to you on that one this coming Monday.

P.s. I think it's roughly about 5 x 4 x 2 units in Unity. Should it be in 1x1x1?
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.

Using Unity Pro 4.3.2f1 Win7 64bit
Just my left monitor.

I'll test it out again on a different machine. See if I can replicate the same result.
Scratch that "reseting Unity part"

Got the same thing again... this time with picture!

P.s. I think it has to do with the way I set my monitor's offset. My main monitor has a higher resolution than either of the two monitors I have.

Edit - I found how how to replicate this issue. When I scroll out of the shader forge, it appears at the top left corner, but if I'm zoomed all the way in. It's fixed.

Something about getting coordinate position when scaled out?
