One of my customers has just informed me that the county (state) drop down in the 'billing address' section of checkout is not working. The drop down does not contain any options and does not allow them to enter an option either.
This is for the UK, but it seems to do the same with with every country apart from 'United States'.
Interestingly, if I type the country rather than select from the drop-down, the county/state turns into an empty text box, thus allowing users to enter a county/state, however if the customer selects a country, the problem occurs.

Is this a FoxyCart bug or have I messed something up in my JS?
