unwanted spel checker

[Lon More]

It seems that a new version of internet Explorer has installed itself. It is accompanied by a Dutch language spell checker,
Most annoying when typing in Engish.
How can I either

disable this
add an English version so that I can switch between languages

Thanks

Right click on one of the 'wrongly spelt' words when it is underlined with a wavy red line, then one of the options will be languages. Click on that and select the one you want rather than the one it thinks you want. Infuriating!

Thanks, as you said, infuriating
