Thread:Talk:ResourceLoader/RL, media=print and print-only style sheets/reply (2)

This is a neat trick. Now the only problem I seem to have is that only when I choose  (to check on which resources are loaded) that the print CSS does its job but as soon as I choose no debug mode the CSS switches back to the on screen CSS while I'm still in. This behaviour was located on a MW 1.20alpha (1a7da4f) test system.
