I searched forums but only found out that Mac users had problems with this. I have Windows 8.1 and WhatPulse does not track my keystrokes at all. http://puu.sh/bp8YJ/399d7f179e.png
I have all the options set to tracking from settings.
Have you tried running it in “Administrator mode” ? That is available in the settings. If even that does not work, check for an antivirus program that could block WhatPulse from receiving input and create a whitelist for the client so it does receive input.
