Stream Deck not accessible?

Hi,

I use Stream Deck and one thing I find annoying is that the Elgato Stream Deck.app hides itself and there doesn't seem to be any way to access it than opening it again. If I have the SD screen saver activated sometimes the keys on the deck are irresponsive and the Stream Deck will only come back to live by opening the app.

I was trying to add an action to one of my unused mouse buttons so that when I clicked the Stream Deck could toggle on and off. Nothing happens. I know it is not a problem with the mouse because triggering the action with a key shortcut yields the same unsatisfactory results. Interestingly I cannot activate the Elgato Stream Deck app via Keyboard Maestro, either.

There's been an update in the Stream Deck software. I'm wondering whether this might be cause. Is there anybody experiencing the same problem?
