Many thanks for your wonderful software that I use for several months now [:)] (and very happy of it!)
By updating today to v5.2a, I got a messagebox “Seems to be your first use of WW”, and I had to reconfigure the options of WW but the city list was kept. I have no login on my PC so just one username. I work under XP Pro.
It could be a bug, but I’m not certain of that because I was not able to reproduce that problem. If it’s not a bug, then your .INI file was deleted from “C:\Program Files\Weather Watcher”.
