remove the 'read only' attribute permanently.

Look at the file properties and make sure that read only is not set ? Sounds
to me like you are trying to do thi from XL instead of setting it on the
file itself.

Alternatively, perhaps you can save it as something else and try the same
thing on the copy ?

HTH.
