change to html code when pushing back button

I am using ckeditor3.5.2 with asp.net. When I make an update to a page, it displays fine and it saves fine. However, if I push the button to go back to the editor, the text no longer shows itself in wysiwyg mode, but instead is wrapped in html code. If I view the source, it renders all of those extra characters as well. I have to exit the page and get back in for it to show up normally. If I save while in the html code mode, it saves <h1>header</h1><p>stuff here</p> etc to the page. Is there a setting to auto refresh so that it renders correctly when I go back to the editor? Thanks.
