Hi I have just upgrade and everything has gone fine however there is a huge blank image over the post editor and a black borderline below the post toolbar.
I have used firebug and the web development tool bar to see where the image starts and end and it looks like it fills the page from the tool bar downwards.(over the tags and options).
The image html is:<img src="images/media-button-video.gif"/>
Once clicked I get the file uploader.
Is anyone else having this problem?
