[users] Keyboard issue

[Maggie Egresits]

I have a frustrating situation with the 'Writer' ----
After typing a half page of E-mail addresses and need for '@' , this
character suddenly not available but rather got a " (quotation mark) 
Same scenario with '#' character -got a / (slash)
Remainder of characters on number keys seem to be accurate.
What is wrong and how do I correct this?????
As you see I am not having this issue with other applications .
