Strange Noises when I click or open program

I have a curious issue with Cubase: When the program is opened or when I click on any action within the program there is a strange audible noise (frequently a different tone) that goes along with it. I have a Mac so I’ve gone into the audio midi setup and attempted to make “notifications” routed in a different way, but that doesn’t seem to make a difference. Its quite loud. Makes any work impossible. Any ideas?
