Runtime error message when opening a word document

[Joan]

Everytime I try to open one of my word documents I get the
following message

Runtime error '-2147352565 (8002000b)':
Can't move focus to the control because it is invicible,
not enabled, or of a type that does not accept the focus.


I am able to open my word document after this message but
woiuld like to get rid of it if possible.
Anyone know how to get rid of this message.


Thanks
Joan
