I think I've found the problem: it seems that the Synaptics Driver simply doesn't work properly with Windows 8.1
5 days ago I uninstalled it, re-installed it and everything was peachy keen for days. Then today it started happening again (middle part not working, scrolling/zooming at weird times etc). I've now uninstalled the Synaptics Driver again and the problem is gone. If you don't use any advanced gestures (scrolling with two fingers, pinch to zoom) simply remove the Synaptics Driver and roll with the Windows driver. It works just fine for me. If the problem should return I'll let you know but I'm pretty sure it's that **bleep** driver.

i only adjusted sensitivity for scrolling and enabled scrolling with sides of the touchpad. but it sometimes does not work when i use mouse, after i disconnect the mouse. weird.
