AutoHotkey script only works when this window is open

Question

Autohotkey script only works when I have this window open (please see screenshot). If I minimise it, it does not work. I have the H visible in the tray. Any help would be appreciated, thanks.

My script to use with Windows Pen is simply:

#F20::Run OneNote ; Single click, Open OneNote

Answer 1

if your keyboard has a f20 key

#F20::Run C:\Windows\write.exe

Would run wordpad.

Supply the path where OneNote is located.

#F20::Run path\OneNote
