Hi all! have problems with mouseover in Mozilla and Chrome after making it work in IE, for sure I can tell you that my code woked perfectly in Chrome at least, cause thats my default browser and I used it for debuging when creating the javascipt and it worked nicely... until I tried to make it work in IE too.

Here I post the full code of the webpage I'm having trouble with.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebbShop.aspx.cs" Inherits="FSwebportal.WebbShop" %>

.prodShow{width: 100%; text-align:center;border:0; float:right; position:inherit; padding-left:310px;}

prodFollow{display:block; width:100%; height:100%; position:fixed; overflow:hidden;}

orderSett{display:block; position:relative; float:left; padding-top:inherit;}

.ShowBig{width:290px;height:290px; padding-top:10px;} .pTb{width:50px;} .order{background-color:Transparent;margin:3px;} .txtArea{border:0;overflow:auto;width:200px;height:100px;} .prodRow{background-image:url("produktbakgrund.png"); background-repeat:repeat;} .row{background-color:Transparent;width:100%;margin: 0px auto;display:inline-table;} .col{background-color:Transparent;width:100%;margin:3px;}

    <div id="prodFollow">
