After updating to Windows 10 some months ago I've got some troubles with my Synaptic touchpad. Generally it's become less sensible so that I need to to tap more than one time and harder to select something. And when I've worked on my Acer Aspire 7745G for a long time the touchpad simply stop working, and the only thing that can make it work again is restarting the pc! A smaller annoying thing is that when drawing a line using the touchpad, moving a tiny bit too fast can make it accelerate out of my control. Hyper-sensibility one could call it! The problems occurs both when using the latest driver from Acer.com Synaptics 126.96.36.199, 2010/04/12, and the one installed automatically with Windows 10, Synaptics 188.8.131.52., 2015/07/14.
