I recently upgraded my site to version 2.5. When I attempt to write a new post, I can enter the title, but clicking on the "Post" entry box automatically brings up the Media Upload box. The "Post" entry box seems to somehow be overlaid with another box (I can see the upper border) and my page is massively long as a result.
I've tried re-uploading files, but I've gotten the same result. Any ideas?
