Getting the browser spell-checker to work with CKEditor in DrupalPublished on Sep 16, 2012
Add the following configuration options:
config.disableNativeSpellChecker = false; config.removePlugins = 'scayt,menubutton,contextmenu'; config.browserContextMenuOnCtrl = true;
Save the profile and you're done. Naturally, you may need to refresh your browser and clear any caches for the changes to take effect.
