When it's working on IE11/Win8.1, I get the HTML formatting that you mentioned above, and while that's a little annoying (because it's hard to find stuff when going into HTML view), I can live with that. But to me, the "copy/paste doesn't work" line actually means that sometimes (read: very frequently) when I copy/paste into WYSIWYG/design view, the paste action crashes IE and on restarting IE, I have lost all of my edits since the last save. That made using design-view impossible, and HTML view just doesn't fly for a long article. This is why I decided to write my article in Expression Web and then send CP the file when it was done. Not sure if this belongs here or in the Site Bugs forum... ?
