I downloaded the hunspell dictionary for id_ID and placed it in the correct place (Common/1.0/Dictionaries).
I can pick Indonesian spelling from the UI but it still shows all spelling as incorrect.
Can anybody help? Much appreciated.
I meant the full name of the directory, including the subdirectory for your dictionary.
For Czech, where the file is named "cs_CZ", the subdirectory of the dictionary is named "cs-CZ".
The same is for basic dictionaries, eg "en_GB" vs "en-GB", etc.
