"open with" Word and editing Web pages

aWhen I try to open a saved Email or Web page with Word, I get an error
message, "Missing file C:\inc\style.css". After a delay, I usually get the
file openned in Word. Sometimes I have to repeat, and sometimes click the
toolbar.

In an unrelated matter, I saved a Web page and tried to edit it with Word,
in order to save part of the page. But the text was inclosed in a box or
frame, which I couldn't get rid of, and I didn't have full editing facilities
within the box. How do I get rid of boxes like that.?
