I am using the windows precompiled build on Windows 10 x64 and a phone running 7.0.

The program starts up fine and shows the screen perfectly, but whenever I left click on the screen with my mouse (on my PC) nothing happens.

Right-clicking does turn on the screen and all the shortcuts work. I do have two monitors on my PC, if that matters.

EDIT: I am using a LG G5 and this seems to be a common problem on LG devices?
