Did you use any of that "Frontpage Draw" and rely on FP to design the
website, thus creating some code that some browsers might not read - you
might have some source code like:
<p><!--[if gte vml 1]><v:rect id="_x0000_s1025"
style='position:absolute;left:12pt;top:30pt;width:74.25pt;height:57.75pt;
z-index:1'/><![endif]--><![if !vml]><span style='mso-ignore:vglayout;
position:absolute;z-index:1;left:15px;top:39px;width:101px;height:79px'><img
width=101 height=79 src="new_page_11_files/image001.gif"
v:shapes="_x0000_s1025"></span><![endif]></p>
Or you are not using a DOCTYPE and IE is in quirks mode. Or your source
code is not correct and some browsers are less forgiving. Or maybe you are
using tables and percentages so 100% in a 800X600 resolution is not the same
in a 1920X1200 resolution
I could go on, but you get the idea. A bit more information from you and we
can be more specific
