No, I know. I didn't mean to imply that BH was converting double line breaks (either <br> tags or \n) to <p> tags, simply the visual appearance of paragraphs (blocks of text with whitespace between.)
And the problem with multiple returns seems to be odd. As I noted, I was posting on IE10/W7. Now I'm posting on Safari 7, Mac OS X 10.9 and returns behave as expected. But then the quote function is also working now (it wasn't this morning on IE10).
As Alice said, curiouser and curiouser...
Edit: (BTW, IE11 was one of the unwelcome additions that came with W8.1, I found that it broke a few websites, including WYSIWYG text editors. Strange that we seem to be having the opposite experience here.)
You'll probably want to install 'normal' apps for the likes of image/PDF viewing and associate them with the file types (W8 associates the metro apps by default). Oh, and kick Bing in the goolies and righteously stamp on its head.
I remember the first time that I installed W8, opened IE and though WTF is everything upside down? And why Bing?
