I’m using two monitors with Cubase, one for the main window and the other for the MIDI editor and Video. When I have the Video window open it always overlaps the MIDI editor, even if I click on the MIDI editor.
Same problem here. The windows in Cubase seem to have a predefined depth (you can’t focus/click it to bring it forward). I find very frustrating too than the EQ window is always hidden behind the plugin windows. I end up dragging those windows to a corner as a workaround.
