IWGhost,

Try / Consider: 

Adjust the delay sense on the TouchPad, adjust the sensitivity level and active "touch" area

Method One:

Start Screen > type anywhere > PC Settings >
Click to start PC Settings (/ Right Click to Pin program to Start Screen) >

PC Settings > PC and Devices > Mouse and TouchPad >>  
Adjust "TouchPad" delay settings as desired

Method Two:

Depending on your computer model, and Synaptics driver type and version, the following may help.

Assumes latest HP / Synaptics driver installed as available for your Product and OS version.

Examples show Synaptics version 17.0.8 - HP Envy 17t Quad - Windows 8.1
