Key editor and workspaces

I have created a workspace in Cubase 10.5 which has the main window on monitor 1 and the key editor & mixer on monitor 2. However, selecting something on a midi track so that it is displayed in the key editor, then deleting it (in the main window) causes the key editor window to close.

This is not ideal as I then have to either reopen the key editor window from the menu or reselect the workspace - is there a setting somewhere which will enable the key editor window to remain open at all times (in accordance with the current workspace)?

Hi,

This is how Cubase behaves. The Key Editor is representation of the MIDI Event. If you delete the MIDI Event, there is nothing to show, so the Key Editor closes.
