Typing error

[Ted E. Allen]

Dear Sirs,
I recently downloaded Apache Office 4, version 4.1.11;  I did so due to an
error in my older version and was hoping by upgrading that the error would
be corrected.  I am using Windows 7.
My error is still there and I tried to figure out if I did something to
make it happen.  What happens is: when I type an* a* and then spacebar, I
get* Mac*. I then would have to erase the M and c just to get the a.
Is there a simple way for me to correct this?
Sincerely,
Ted E. Allen
