spellcheck language inconvenience

I must be missing something here, I'm sure. I am using Windows Live Mail. Here's my inconvenience:

I write a complete email in Spanish and when it comes time to spell-check it I find that my default compose language is English. So I have to change my default language and re-write the entire email from scratch? Doesn't make sense; I should be able to change spell check language from within the (already written) message. Can I? Am I missing something?

Hello Maxie. It does not answer my question, but thanks nevertheless. I guess one must remember to set the default language before one starts writing the message because once the message is written and every second word is underlined as a mistake, there is no way to change the default language and spell check in the new language: one must simply re-write the entire message once the new default language has been selected.

Once again, thank you.

To give you an example. Set your language to English and write a new email with just the word mañana. It will show underlined as a mistake. Now try and change the default to Spanish until mañana in your email is no longer shown as a mistake.
