How do you change the Google Toolbar spellchecker to English (GB)?

I keep getting red lines under words like colour and rationalise.



And if it isn't possible could anyone direct me to a web browser spellchecker which isn't going to make a dyslexic simpleton like myself come across as a yank.



Thank you.

I was able to right-click on the multi-colored font Google button in the toolbar and select Google Toolbar Options. The General tab is where the language setting is - change yours to English (UK)



Good luck from a %26quot;yank%26quot;
