Ok again.

Now the fun begins.

Let's say I didn't like this and I wanted to switch it back?  Oh well, no luck.

When you go back and uncheck the gray scale button, it doesn't switch back.  On top of that, if you you click on another part of the shader tree and go back to it, the box to select the option also vanishes.

And so ends my story of the infamous wires bug.
