problema select in opera

[mattealex]

ho questo codice:

<div class="contentInputTableSelect"><select class="inputTableSelect"  name="material">
    <option value="1">uno</option>
    <option value="2">due</option>
    <option value="3">tre</option>
    <option value="4">quattro</option>
    </select></div> 

con queste proprietà:

.contentInputTableSelect{
    overflow:hidden;
    background-color:#CEBD78;
    border-style: solid;
    border-width:thin;
    border-color:#000;
    border-radius: 6px;
    -ms-border-radius:6px;;
    background-position: 98% 50%;
    background-image:url(../imgs/fdown.png);
    background-repeat:no-repeat;
}
.inputTableSelect {
    text-align:left;
    width: 120%;
    background-color:transparent;
    border:none;
    font-family: "Myriad Pro", "Myriad Pro Cond", "Myriad Pro Light";
    color:#000;
    padding-left:3px;
    padding-right:3px;
    -webkit-appearance: none;
} 

in opera il select mi risulta bianco.
Come posso risolvere?
