Comment 2 for bug 747733

I don't know if it makes a difference, but I instinctively tried to select my town by entering my ~zip code~ into the dialog box. Since nothing seemed to happen, I deleted that and entered the nearest major city, then I noticed my actual smaller town had been populated into a drop-down menu, but not into the select box. I believe I tried to then select my town from the drop-down, in lieu of searching for the city I had entered instead.

After submitting this bug report, and closing the original dialogs and starting over, I entered the name (not zip code) of my actual town, clicked get cities, and it populated the select box itself correctly. I was able to continue without incident (I did no other configuration besides setting my location).
