Input text switching to US keyboard on upload

Hey Folks,

Never had this problem EVER so im stumpped. Basically, im from the uk and had created a website with a few text input fileds. Everything was working fine when playing in Flash but I have now uploaded the site and every time i press the @ symbol, i get " . I know that this is common place if you have your keyboard language set to US in vista and alike but I am stumped as to what would be causing this when uploading to my server.

Anyne got any ideas?
