This is code I copied using Firebug. Does this help? I don’t know enough about the coding to tell if anything is wrong or if I copied the right section.
Thanks for your quick reply. I tried re-uploading wp-includes/js/quicktags.js as you suggested. It didn’t make any difference.
I’m not sure what I would be looking for as far as any js erros.
