I have installed the "After the Deadline" extension for LibreOffice 3.6.3, but it does not pick up any grammatical errors, either as a wavy blue line while I type, or with a complete spell check of the document. How can I get this to work?
Select Tools -> Options -> Language Settings -> Writing Aids. Click the Edit... button under the Available language modules section. Make sure the After the Deadline option is selected under the Grammar section.
