Hello, I run last WW version on Vista 64. First of all, it used to work well before I did some play with Windows Sidebar/Explorer settings! I just reset my Internet Explorer 7 settings to defaults. That's all. I also did a try to the sidebar weather applet in sidebar. After this play, WW IS BROKEN IN AN INCREDIBLE (for me) WAY. To try to solve everything fast, I removed WW and install it again becouse it started asking me if I want to install a new map at any new reboot or log on/log off in any account of my Vista 64 machine. It happen EVERY TIME AT EVERY REBOOT OR LOG/ON-OFF and it stopped update the weather. So I removed the app, carefully deleted everything even in %APPDATA%\roaming\weather watcher folder and reinstalled the app! It is INCREDIBLE: even after reinstall, as I said, it keep asking me for new maps and backup EVERY TIME, main program window do not appear and searching for a city stay forever on search! What happen??? Thankx from this satanistic pig if u can help!
