Weird things happening

I’m asking many things, I know, but I’m finally starting to explore the C11 upgrade and a lot of functions I’d never used in the past…

  1. sometimes, when I try to give a keyboard command, a message appears on the screen saying something like “the on-screen keyboard stopped this command” but I never activated the on-screen keyboard…

  2. trying to export a four chord midi track, generated starting from the chord track, but the audio file is shorter rhan the midi notes are (see screenshot); when I play the midi track it sounds correct…

Thank you for helping!
