-sender adds buttons

[FedericoJoly]

Hi juliebnXX, thanks for this amazing piece of software!

I think there's a bug when adding the -sender option. I'm using it to customize the notification message.
By adding it, the notification turns into an alert, by adding the buttons 'close' and 'show' so it doesn't disappear after a while, only when a button is hit.

Kind regards,
Federico.

Tried 1.8.0 as well with same behaviour.

Thanks!
