I think I already responded to your email inquiry on this issue, but for the record, try adding these lines to your View Cart code on every page where you are using our View Cart button, just before the "// -->" line in the standard code we issue:
function EJEJC_config() {
EJEJC_INITCSS = false;
}
This fixes some common problems that can be caused by a conflict between our cart's CSS and your own page/site's CSS.
