Hi,
about the language changing,the problem is that you have more languages putted at control panel, i have two language putted too: Hungarian and Romanian, i don't know but i press some buttons and it changes to Hungarian most times. You can remove one language or more at Start>control panel>Regional and Language options>languages>details>remove.
About the typing box,i can't help,maybe your "T" button is not working at all.
I hope,that the my assistance has helped you.
