web preview not same as publisher view

Reading past postings it appears others too are having serious problems with
Web preview in both 2002 and 2003. I think the problem is that text handling
within text boxes in normal Publisher view simply does not reflect that as
seen in Web Preview (currently Explorer 6) On a totally blank (wide setting)
webpage, using standard Times New Roman 12pont (no italic underline or bold)
I typed six lines of Mary had a little lamb into a 3.85x3.029cm text box with
all margins set to 00. I outlined the box with a 1/4pt line Whereas the
text just fitted into the box in Publisher view, in Web Preview whilst the
box size was unchanged, there was a large gap between the text and the right
and bottom margins of the box. This surely suggests a serious problem with
either line spacing, text size or margin setting. This problem could NOT be
reproduced in Publisher 2000. 3 questions - Have I got some settings wrong,
and if not, why can't Microsoft resolve this problem and what is so
drastically different between 2000 and later Publisher versions that can
cause this problem, which makes laying out pages accurately virtually
impossible.
