Keyboard commands have stopped working. For example pushing the space bar no longer starts PLAY. The delete key no longer deletes a selected item in the timeline. I guessing that I might have accidentally hit a keyboard key that toggles this functionality on and off perhaps?
By the way it’s not a faulty keyboard. I’m typing this post using the keyboard.
One of my students experienced this as well few week ago on Nuendo 5.1.
She finally narrowed it down to open media bay window. Hasn’t happened to me or anyone else tho…
Also open Waves plugins windows can cause this.
These are all that comes to mind.
Also might be worth trashing prefs and see if that helps.
