【Bug】OM-UI的omTab的默认样式，在非FF浏览器下无法滚动的问题

在做多个系统时都使用到了om-ui框架的系统，在非FF浏览器下页签上出现较多tab时无法自动滚动。经过多次测试，发现了apusic样式没有这个问题
于是查阅om-apusic.css，找出不同点，然后修改
以前的代码：

.om-tabs .om-tabs-headers {
    overflow: hidden;
    padding: 2px 0 2px;
    position: relative;
    _width: 100%;
    border:1px solid #86A3C4;
    border-bottom-width:0px
}
.om-tabs .om-tabs-headers .om-state-default a{
    color: #23466D;
}
.om-tabs .header-no-border{
    border-width:0px;
}
.om-tabs .om-tabs-scroll-left {
    background : url(images/tabs/om-tabs-scroll-left.gif) no-repeat;
    height: 29px;
    left: 0;
    position: absolute;
    top: 1px;
    width: 18px;
    cursor: pointer;
    z-index: 100;
}
.om-tabs .om-tabs-scroll-right {
    background : url(images/tabs/om-tabs-scroll-right.gif) no-repeat;
    height: 29px;
    right: 0;
    position: absolute;
    top: 1px;
    width: 18px;
    cursor: pointer;
    z-index: 100;
}
.om-tabs .om-tabs-scroll-right:hover {
    background-position: -18px 0;
}
.om-tabs .om-tabs-scroll-left:hover {
    background-position: -18px 0;
}
.om-tabs .om-tabs-scroll-disabled {
    background-position: 0 0 !important;
    cursor: default;
    filter:alpha(opacity=50); /*IE透明度50%*/
    -moz-opacity:0.5;         /*Mozilla :Chrome  360  透明度50%*/
    opacity: 0.5;             /*Firefox Safari Opera透明度50%*/
}
.om-tabs .om-tabs-headers ul {
    width: 5000px;
    font-size: 12px;
    margin: 0 ;
    padding: 0 0 0 4px;
    border-bottom: 1px solid #86A3C4;
}
.om-tabs .om-tabs-headers ul.om-tabs-scrollable {
    padding : 0 23px;
    position: relative;
}
.om-tabs .om-tabs-headers ul li {
    background: url("images/tabs/om-tabs-bg-d.png") repeat-x scroll 0 0 #DCF0FB;
    display: inline-block;
    margin: 0 4px -1px 0;
    padding: 0;
    position : relative;
    -moz-user-select: none;
    float: left;

}
.om-tabs .om-tabs-headers ul li.om-state-hover{
    background: url("images/tabs/om-tabs-bg-h.png") repeat-x scroll 0 0 #DAEAFA;
}
.om-tabs .om-tabs-headers ul li.om-tabs-activated {
    border-color: #8DB2E3 #8DB2E3 #FFFFFF;
    background: url("images/tabs/om-tabs-bg-a.png") repeat-x scroll 0 0 #FFFFFF;
    font-weight: bold;
}
.om-tabs .om-tabs-headers ul li a.om-tabs-inner {
    text-align: center;
    text-decoration: none;
    outline: none;
    white-space: nowrap;
    float: left;
    padding: 0 10px;
}
.om-tabs .om-icon-close {
    float: left;
    margin: 0.4em 0.2em 0 0;
    cursor: pointer;
}
.om-tabs .om-tabs-headers ul li a.om-icon-close{
    background: url("images/tabs/om-tabs-closebtn.gif") no-repeat;
    display: block;
    height: 10px;
    width: 10px;
    margin: 7px 6px 0 0;
}
.om-tabs .om-tabs-headers ul li.om-state-hover a.om-icon-close{
    background-position: 0 -9px;
}

.om-tabs .om-tabs-panels {
    overflow: auto;
    margin: 0;
    padding: 0;
    border-width: 0;
    position: relative;
}
.om-tabs .om-tabs-panels .om-panel-body{
    padding:1em;
}
.om-tabs-noborder {
    border-width: 0;
}

修改后的代码：

 }
