Confluence 4.0 Editor, cannot scroll to the bottom of the window.

[Steve Knights]

We are experiencing issues whereby the user is unable to see the last 7 or 8 lines of a page within the editor window. The cursor will disappear below the bottom of the window. As a workaround we have scrolled to the bottom of the page and put carriage returns to fill the bottom of the page allowing users to see all content but this is not an acceptable solution.

I think there might be some error in your theme. You might want to switch back to the default theme to see if the same error occurs. Then you can compare the differences to make the necessary amendments.
