Browse buttons not appearing

I have installed the FCKeditor (nightly build from the Jan 16th) with MediaWiki 1.11.0 and everything appears to be working except the browse server and browse image buttons do not appear. The MediaWiki documentation on Extension:FCKeditor shows several places the MediaWiki php files must be hacked. These files include EditPage.php, Parse.php, and SpecialPreferences.php. The instructions of exactly where these changes go is vague. The guide lists functions in the php files and code that should go before and after the function. I am not sure if they are referring to the function definition or each instance the function as it is called. All of my attempts to implement those hack either did nothing or broke FCKeditor. Has anybody else solved this missing button problem?

I tried installing the MediaWiki+FCKeditor version of things which I got from http://mediawiki.fckeditor.net/index.php/Main_Page. I tried their sandbox but the buttons still did not appear. I did see the buttons when I used one of the sample php files from the standard FCKeditor package with no MediaWiki integration. Could this be a browser version problem or is this feature not working with MediaWiki?
