Proofreading only in English

[jonezjea]

If the interface is in Dutch or when the Dutch language file is active, why does the proofreading only uses English? It is annoying to use it on my Dutch blog because I don't write in English.

This is a minor complaint so it isn't urgent

If by "proof reading" you mean the TinyMCE spell check then it does support Dutch. On the editor click the little dropdown arrow to the right of the spell check button ("ABC" over a tick mark) and select the language of choice.

Or use the mce_spellchecker_languages filter.

Or use a browser that has build-in spellchecker (all except IE).
