Tabbing past Datepicker control

Tabbing past Datepicker control

Hi,
 
I am having a problem where I have to hit tab twice before my datepicker control will lose it's focus.  No matter if you type in a date, or select a date from the calendar the next control won't gain focus until you hit tab a second time.  The first time you hit the tab button the calendar disappears then the second time the next control with get the focus.  The desired response is that the first tab will close the calendar and also move to the next control on the page.  I am using jquery 1.7.2
