Combo box is lloking like Text box in Safari

Hi
Can anyone help me ??
I am using combo box widget control in my page, but in Safari it is looking like a text box. How to make it look as Combo box??

Thanx

I am using AW - 2.5.1

Do you see the same problem with the standard examples? Did you copy all images together with aw.css file? In which version of Safari/OS?
