happens for me when using the “edit instrument” key command on all Cubase versions since sampler track introduction. I have a windows system and a macbook, both have the same issue regardless of preferences, templates, clean project etc. Makes it completely unusable for me which is really frustrating as I still need to use third party solutions.
Either steinberg is not aware of that or they ignore it completely.
