IE 6 problems
I've had problems also, looks normal with IE 7 but customers using IE 6 don't see it at all or have problems. For example IE7 will have horizontal menu buttons between the banner and the body and IE6 viewing will put it above the banner.
This is also true for SiteAssist. It will look fine in IE7 but images and areas will be pushed down and over. It is embarassing to have a client looking at it in IE6.
I really think that WebAssist should created a PDF that tells us what to look for. These are products that promise not to need special coding skills, but these problems are hard for non-coders and non-CSS experts to solve.
Had the problem with Site Assist and thought that Site Assist Pro would solve it but it did not. I'll also post this in the SiteAssist section.
