Version - 7.2.75
Tray Icon shows N/A and when rolling over tray icon, no weather info is displayed.
I have Windows 7 with all available updates and this did not start until I did an update of Windows yesterday.
Just downloaded newest version of WWL and installed today after tray icon was not displaying information. Thought it may have been WWL.
Possibly not because after update WWL tray icon still has no weather information.
