I was having an annoying problem with my Samsung AtivBook8’s touchpad. The touch pad’s control panel applet was not saving the “two finger scroll – reverse” setting.
Unchecking the reverse option did appear to work initially – the page scroll direction does indeed go back to normal – however on restarting the machine the setting always reverted back to being enabled.
This was driving me mad! Fortunately it can be fixed:
1) Uncheck the “reverse” option for two finger scrolling in the control panel applet. Close the applet.
2) Using RegEdit change the following changes to the registry:
HKCU\Software\Elantech\GroupOption\SmartPad\SC_Reverse_Enable = 0 HMCU\Software\Elantech\SmartPad\SC_Reverse_Enable = 0
Making these changes turns off reverse scrolling for good. At least it worked for me.
