On EmEditor Professional v10 or later, you can check spelling without using any plug-ins. On the Context Menu of EmEditor (the right-click menu), selecting Check Spelling will enable spelling. If this menu item is not visible, you can select Customize Menus on the Tools menu, select Context Menu on the list, and then click the Reset button. Additional dictionaries are available for download at the extensions.OpenOffice.org (http://extensions.openoffice.org/). After download a dictionary, change the file extension from .oxt to .zip, extract the Zip file, and then copy *.dic and *.aff files into the Dictionaries sub folder of the EmEditor install folder (usually "%LOCALAPPDATA%\Programs\EmEditor\Dictionaries" or "C:\Program Files\EmEditor\Dictionaries").
