I copy/pasted the line "

I pasted it into the window shown in post #6.
I didn't edit anything in the text box. I just checked and it doesn't allow me to (as you were saying -- I hadn't noticed previously), so edit first, then paste. (I guess my workflow is more akin to what was expected by whomever designed the interface.)
That kind of behavior I am fairly certain is hard-baked into the forum software, so I doubt it could be changed easily.
