Hi there. Yeah, the same thing happens to me: I let the notebook downloading for a few hours overnight and when I check in the morning, the program is stuck in memory. In fact, it ceases to function but Task manager cannot kill the apllication nor can the Resource Monitor. I have to reboot the machine in order to make it go away and be able to use it again, when after a few more hours, stopps functioning again with the same results. It's been behaving this way since i made the update to build 22150. It hans't happened ever before this... Cristiano.
