combo dropdown displays after several clicks

Hi,

I used AW 2.0 beta version. The AW.UI.Combo box does not display the drop down immediately on the first click ( on down down button in combo), but displays after few clicks. Is there any work around or can we manually trigger the event to display the dropdown or are there any method to display the dropdown list. If so, which event do we need to trap/override.

Tks in adv.
