I completely understand how the button works, as I have used it before. I tried restarting the client and that did not help. I tried restarting my laptop and that also did not help. I am using stealth injection, so I do not know if that makes a difference at all? I have tried all the options available, such as: Mouse & Keyboard and just Keyboard. The mouse only works for me when it is set to both Keyboard & Mouse on the input settings.
