I upgraded to 2.5.1 over the weekend, and I'm getting this issue when I try and either write or edit a post.
As soon as the post.php or new-post.php loads, the "Save" and "Publish" buttons start flashing, like I'm clicking on them, and it saves the post nearly immediately. This becomes a problem cos it reloads the page, and essentially stops you from freely writing the post.
I've had this issue in both Safari and Firefox 2.
Can anyone help?
