First, I have had tons of problems with any WYSIWYG editor in block code; if there is any way to not use an editor there, I would take it.

I assume that you are user/1, or at least an trusted user, so try switching to "Full HTML" or even no filter and see what happens.

NO editors installed.
Still something is inserting backward slashes  before quotation marks. Any ideas?
