```hs.alert``` not always working

[Badsheep]

Hello,

In my Hammerspoon config I use hs.alert when keys are stroked, for example :

hs.hotkey.bind({"ctrl", "shift"}, "n", function()
      hs.alert.show("Compresseur activé")
      end)

When I start the script, it works fine. But after some time (some hours ?), the alert doesn't display anymore.

But what is interesting to resolve this bug, when I open the Hammerspoon console, then it starts working again. Strange, no ?
