Pub isn't perfect, you don't always get the exact same thing, some trial and
error is common in the design process. But I may be able to offer some
suggestions with more information.
what browser is used for viewing?
what display resolution is used on the PC?
what page width is the web publication set to?
did you set a custom height?
are you using a master page?
do you have any objects in the scratch area?
are you using html code fragments?
if so do they contain html or javascript?
did you create a web publication or convert a print publication?
did you upgrade an older version file?
are you applying any formatting to the text paragraphs?
are you formatting the images?
are you inserting any objects?
The more you can explain the web publication and explain how you designed it
the better I can point out trouble areas. You can also gain education by
using the FAQ -
