This is very strange. I am using the leaked WM6.1 (beta). And I get zero notifications, and notice that WeatherPanel does show the current temp, when I turn back on.
But as soon as I turn on, the connectivity bubble pops up, and it checks email, and updates WeatherPanel.
Is there a registry edit that tells the device not to connect to the internet if in standby? (maybe something for battery saving)
Never had this problem with the 3.35 ROM, and I am running the exact same programs.
