As of upgrading to 3.5 I've noticed that the Visual/Text Editor on the back end defaults to a length that is much longer vertically, than my screen and requires reducing it sometimes as many 4 scrolls of the screen to return it back to normal. To try to counter around this, I started using the full screen editor, and upon the first minutes of writing it worked fine. When the text got to be longer than the screen could display, it forced the browser to go back to the all posts page. Upon return back to writing a post, it began happening on the full screen editor as well.
Is anybody else having this problem? What can I do to try to fix this?
