Background image css opera issue

Am having 开发者_如何学编程an issue in opera. I have a series on hyperlinnks in a ul li with backgorund images applied. The pointer cursor isnt displaying when I hover over the links.

Is this a know bug, code below

#sidebar ul {
margin: 0;
padding: 0 0 27px 16px;
display: block;
float: left;
width: 180px;
}

#sidebar ul li {
background-image: url(images/left-nav-bg.jpg);
background-repeat: no-repeat;
margin: 0;
margin-bottom: 10px;
padding: 0;
display: block;
float: left;
width: 180px;
height: 40px;
list-style-type: none;
cursor:pointer !important;
}


#sidebar ul li a {
background-repeat: no-repeat;
background-position: 2px 2px;
margin: 0;
padding: 8px 8px 0 4px;
display: block;
float: left;
width: 168px;
height: 32px;
color: #ffffff;
font-family: Helvetica, Arial, sans-serif;
font-size: 18px;
font-weight: bold;
text-align: right;
cursor:pointer !important;
} 

you should use hover stage for this id

#sidebar ul li hover{
background-repeat: no-repeat;
background-position: 2px 2px;
margin: 0;
display: block;
float: left;
width: 168px;
height: 32px;
color: #ffffff;
font-family: Helvetica, Arial, sans-serif;
font-size: 18px;
font-weight: bold;
text-align: right;
cursor:pointer !important;
}

add this css in your style.

Issue solved, changed mouseover and mouseout events to be return true;
