Country, state/province selection does not work correct

Core 1.8 beta 10576, item 1 and 2 also verified on the demo site

In editing contacts:
1) Select country or select state/province: only the first 5 country's / states are shown. The pop up is slow. You can not roll down

2) When deselect all available countries and states in global setup the countrie and state labels are stil present in edit contacts and all the available countries are shown when selecting the pop up. The states pop up has the (stored contact ) state or the basic select text

3) I have succesfully transferred a 1.7 database to 1.8. The database is filled with Dutch contacts.

When my default country is the Netherlands (global settings/localisation) and also available countries and states/provinces are "Netherlands" my country pop up in edit contact shows "Nederland" (the translation of the Netherlands) AND "Netherlands". The default is "Nederland" You van select between the original country " Netherlands" and the translation "Nederland" When I leave the countrie "Nederland" the state/province shows the province of the contact selected in the original civicrm 1.7 version (stored in de db). That is correct, only the province pop up does not work and you can not change the province.

When i select "Netherlands" n the country pop up the "Nederland" tekst in the pop up dissapears,, the province pop-up goes to select and when you click the pop up you can only select the first 5 provinces. (item 1)
