Hi,
Since this version i can't use the vertical/horizontal scrolling areas
from my laptop (Sony Vaio Z1 series)


your xorg.conf is broken


Section "InputDevice"
	Identifier	"Synaptics Touchpad"
	Driver		"synaptics"
	Option		"SendCoreEvents"	"true"
	Option		"Device"		"/dev/psaux"
	Option		"Protocol"		"auto-dev"
	Option		"HorizScrollDelta"	"0"
	Option		"ZAxisMapping"				"4 5 6 7"
	Option 		"TapButton1" 				"1"
	Option 		"VertEdgeScroll" 			"true"
	Option 		"HorizEdgeScroll" 			"true"
	Option 		"VertTwoFingerScroll" 		"true"
	Option 		"HorizTwoFingerScroll" 		"true"
EndSection


you should use
	MatchIsTouchpad "true"
rather than assigning devices manually.
See below the log that your configuration generates:

Hi,
If autoadd is on, then using the up arrow key generates a printscreen event :(
