FCKConfig.FirefoxSpellChecker = true ; // This option enables the Firefox built-in spell checker while typing. Even if word suggestions will not appear in the FCKeditor context menu, this feature is useful to quickly identify misspelled words.
FCKConfig.ImageDlgHideAdvanced = true ; // This option allow you to hide the "Advanced" tab in the "Image properties" window. By default it is set to 'false' so the tab is active.
