Apart from the /editors file which other files control the HTML area editor.

I assume that since I haven't changed any files, its a file incorrectly uploaded due to FTP issues, when i have re-installed a back up.

My modem doesn't like ftp, and is ready to be thrown out the window, just wondering if anybody knows so I can narrow down any files that may have become corrupted during the ftp process. (I can use win merge but it will take me around 6 hours to bring the site back across to my drive, like i said ftp issues!!!!)

I have already checked and reloaded /editors and /admin/includes/htmlarea.php is there any more?
