wmp skin help

Hi,

I am making my own WMP skin as project for my school. I have used a
listbox in my skin but the listbox does something very strange. When i
click one time on the listbox (to slect the listbox so I can choose an
item), it moves to above and a little bit to the left. I can use it
then but it's not at the position I want. If I close the listbox
(listbox.dismiss() ) en reopen it (listbox.show() ), it stays at the
same place. But the first time it moves. Can this be a bug???
Here is the code I use for the listbox:





scriptfile :


function openURL() {
keuzelijst.show();
}


function KeuzeVideo() {
if (keuzelijst.getItem(keuzelijst.SelectedItem)=="Via Website")
{
player.LaunchUrl("http://www.google.be");
}
else {
if (keuzelijst.getItem(keuzelijst.SelectedItem)=="Manuele Ingave")
{
keuzelijst.dismiss();


}
}
}


P.S. : Sorry for my English if there are any faults in it!!
