It's intended to toggle on and off a rainmeter skin, and it works fine when the full code looks like this:
If I click Run it will generally always work.
But if I add a hotkey function, and make it look like this:
Run, C:\Program Files\Rainmeter\Rainmeter.exe !ToggleFade "Note"
It won't work every time I press the hotkey. 50% of the time, nothing happens.
