I have just checked and Yo Window is allowed on my firewall Wally.
I went back to check the weather this evening and everything has reverted back to when I downloaded it again the other day, with the weather for New York, Cairo and Japan, so I have set it up the way I want in Options again and put back on the list the Places I want the weather for and will give it another 3-4 days to see if it remains the same.
I am not sure what else I can do to make it remain the way I want it to....On the upside at least I didn't have to re-download it again this time
