C 11.0.40 keyboard input from arrows up and down glitch

since the update my up and down arrow function to move a part from one track to the next works erratically.
select part>click arrow down to move to the next track (stacking harmonies etc.) does not move the part sometimes. have to select another part, then go back to the part i want to move. sometimes it requires a few back and forths.


In this case, I would try to start Cubase in Safe Start Mode [Disable preferences]. If it works with the disabled preferences, I would delete the preferences.

i’ll try that.
