the highlight of selected option is gone

i recently upgraded to dhtmlxcombo 1.2 and noted that the highlightning of options when the cursor is over them is not happening anymore.



is that intentionall? or maybe a problem of this version. how can i get this behavior again?.



thanks for the help.

Just add next style to used css file

.dhx_combo_list div:hover{
    background-color:#C8D7E3;
}
