I don’t see now the temperature but only a white squarred in the systray !
You can modify the tray icon colors in the “Tray Icon” → “Colors” section of the Weather Watcher Live Options window. If you’re not able to resolve this issue from there, then please post a screenshot of that section of your Options window so I can see what your current settings look like.
Good shot and tks ! All is ok now after I have changed the setup in the tray icon color!
