Document flags nearly all words

[Jan Te Lagen]

Hi.

I just started a document in word, and had to insert a non-English letter (é) into a word. As soon as I did that, Word subsequently began to flag (i.e underline in red) almost every single word as wrong, and upon checking it to offer me the not very helpful "no suggestions". Up until the point where I used the é, everything is as normal. Does using these non-English letters freak word out? And is there a way to stop it questioning 95 per cent of the words I use?

Thanks for any help people can offer.
