Enable spell check but disable intrusive grammar and thesaurus

Enable spell check but disable intrusive grammar and thesaurus

Hi,

I don't mind the spell check when I am composing mail. It is useful for identifying typos.

I find the grammar checker REALLY annoying. I am a native English speaker and know exactly what I mean to write.

That is not as annoying as the absurd suggestions I am thrown by some thesaurus algorithm, many of which carry meanings very different from what is being written.

Is there any way to disable these useless and intrusive features and keep the simple spell check?

Thanks in advance,

Rob
