Pure idiocy. There is some kind of caching function - when the touchpad stops working, signing out and signing back inagain often works, while restarting does not. I do not have keyboard caching turned on, so WHY Dell feels it is OK to capture and record my mouse movements is troubling - but having the touchpad randomly malfunction, which has caused loss of work on multiple occasions, is really messed up. My older Dells never had this issue - how hard can it be to figure out what you have changed? I mean really! Signing out and back in randomly is not how computers are supposed to work. But when Dell sends updates on their own, if I decline to install them at the moment, the ONLY option is a no-warning reboot exactly 24 hours later. Has everyone at Dell retired and handed their jobs over to their children? What is going on? This is completely unacceptable and yet no fix is out for Dells running 8.1 so that the touchpad remains operational OR that the updates allow you to choose an interval yourself for them to be installed AND give you notice just before so that you can save your work. It's like Dell is being run by pod people, honest-to-god it does!
