Problems with Firefox 3 - ComboBox

Using Firefox 3 i've got a few problems with the following code:

var input7 = new AW.UI.Combo;
input7.setId('input7');
input7.setItemText(['Auftragsübersicht','Bildschirm-Protokoll','GW RAB','GW Rechnung','KD Lstg. Protokoll','KDB Auswertung','KD-ET RAB','KD-ET Rechnung','Konten-Umsätze','Lohnstundenliste','Monatsabrechnung','Monatsabrechnung Team','NW RAB','NW Rechnung','Stempelnachweis']);
input7.setItemCount(15);
input7.setControlText(['Auftragsübersicht','Bildschirm-Protokoll','GW RAB','GW Rechnung','KD Lstg. Protokoll','KDB Auswertung','KD-ET RAB','KD-ET Rechnung','Konten-Umsätze','Lohnstundenliste','Monatsabrechnung','Monatsabrechnung Team','NW RAB','NW Rechnung','Stempelnachweis']);
input7.refresh();
input7.getPopupTemplate().setStyle('width', '200px');
input7.getPopupTemplate().setStyle('height', '100px');
input7.getContent('box/text').setAttribute('readonly',true);

Internet Explorer 7 and Firefox 2 is working fine, but Firefox 3 doesn't display the select value of the combo box and didn't use the width setting in the right way.

The PopUp windows is 200px width, but the scrollbar is desplayed at the middle of the combox box.

Are there any mistakes in the code or is it a bug in active widget ?

ok haven't got the newest version,....

after updating there is still one problem. The width of the popup isn't set correctly.
