ondown event.
using the vtour droplet in order to have the thunbs close auotmatically they are coded to an onclick event. viewing the thumbs on my iphone they never close since there is never an onclick event that happens. we need an ondown event to replace the onclick for touch devices.
EDIT: I just tested the onmousedown event and it does work. I did not think it would because it stated mouse. Maybe it is called onmousedown but the mouse part is not needed it works for touch also.
