Scrollbar issue on comboboxitem..

Hi,

Vertical Scrollbar appears on comboboxitem component in Firefox but not in case of other browsers viz. IE, Chrome etc.

If picklist has a single entry I am unable to select it with a mouse click. It works perfectly fine in IE and Chrome.

Please suggest possible option to avoid vertical scroll bar appearing in Firefox for ComboboxItem.

Smartclient version: smartclient 8.3
Browser: Firefox 28.0

Thanks,
Bhushan
