After upgrading to Windows 10, after waking the computer from sleep, 3 finger swipe gestures (to minimize all windows or to go to task view), stop working. 3 finger click still brings up Cortana. I'm on a Lenovo Yoga 2 Pro using the Windows 10 18.104.22.168 touchpad drivers. Any help is appreciated!
Edit: This isn't a duplicate of the question linked by Ramhound. That question concerns a touchpad being completely disabled after sleep. In this case, only three finger swipe up doesn't work; everything else is totally fine. The solution is to restart "synaptics touch pad 64 bit enhancements". I don't have access to the laptop in question at the moment, but a simple "taskkill /IM SynTPEnh.exe" will end the process. The process will automatically restart. You might want to put this command in a batch script and schedule it to run on wake up, though I haven't been able to successfully use the Windows event system to do this, and just manually run the script on wake up.
