Sounds when clicking with mouse

As in the topic: I’m constantly hearing short notes when I click with my mouse in the editor windows. All the time it’s a low note from either Bass clarinet or Bassoon (they alternate). I’ve tried several options provided by other users who encountered this in the past, to tackle the problem, like changing mouse speed, changing sample rate and so on, but nothing helps and it becomes really annoying.

I’m on Windows 10 64 bit, i7 4790, 64 GB of RAM, VE PRO 7, Cubase is at 10.5.12 and my audio interface is komplete audio 6.
All help appreciated.
