The observation is that 99% of the time, a single click on a city will put the white box around the city name, fill the background blue and show the correct images. But in some cases, the single click puts the white box around the desired city, puts the blue background somewhere else (always seems to be above the selected city by about 10 - 12 cities) and it shows the the images for the city outlined in blue. Double click on the desired city and then the blue background is moved to the desired city and you get the correct images.
I have tried this many, many times with a wide range of cities, and the results seem to be random. Most of the time, a single click on a given city loads the correct data, but on occasion you get the behavior documented. For a while yesterday, I was convinced the problem magically went away. I could not reproduce the problem. But then, when I tried today, I get exactly as documented. It seems to happen with some cities and not with others, but that may be because it is statistically a low-probability event.
