Arrow down doesn't work as expected

Hi

Sometimes I experience that the arrow keys doesn’t work. Ex. arrow down should select the next track below the one currently selected, but nothing happens. If I hit arrow up it goes up to the first track!!

Okay, now this bug also appears in the Key Editor: https://www.steinberg.net/forums/viewtopic.php?f=286&t=148795

Yes I’ve noticed this as well!

+1 I have the same issue quite often. When I try to transpose notes in the key editor, suddenly it doesn’t work and the previous/next track is selected instead in the track edit window (which I have open on a separate screen all the time). The only workaround is to close the track edit window temporarily, and after a while it will work again. Please fix this, it’s really annoying.
