Same problem, brand new WordPress installation:
Whenever I try to edit a page, it immediately posts back to the server after loading the editor. When I click New page, it opens the editor, posts back, opens the editor, posts back and so on, so I end up with a bunch of empty pages. I have disabled every single plug-in and every single pop-up/ad blocker and tested this in both IE and Mozilla. This seems to apply to comments as well, but not to posts.
It all works when I disable the visual rich editor…
This has absolutely nothing to do with .htaccess files or permalinks.
