I am using a "Custom Dictionaries Folder" in Settings > Editor > Spelling. The *.dic files are picked up and listed under "Dictionaries" together with the default project dictionaries. The *.dic have the one word per line format.
The spellchecker still reports typos for words in the custom dictionary, i.e. the custom dictionary is not honoured.
If I add the words to "Accepted Words" then spellchecking uses them.
How can I further debug why the custom *.dic files are not read correctly before issuing a bug?
