How to get your Lenovo Ideapad 110s trackpad to work properly in Minecraft

I did a lot of digging, found this post, and it gave me the vital clue.

You'll need to change a registry entry... 

Navigate to "HKEY_CURRENT_USER\SOFTWARE\Synaptics\SynTP\TouchPadPS2"

Then change the entry for "PalmRT" from 1 to 0

Exit the registry editor, and reboot.

Here's the text of my patch entry for the registry:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\SOFTWARE\Synaptics\SynTP\TouchPadPS2]
"PalmRT"=dword:00000000
