'S' key doesn't solo track when editor is open

‘S’ key doesn’t solo track when editor is open - title says it all. this used to work in older cubase version. when i have the editor window open for a track, hitting “s” on my keyboard should solo the track (it is still selected afterall) - but it doesn’t work. So when the editor window is open for a track i have to click the solo button in the editor. what gives?

Windows 10 x64

Which Cubase?

solo in editor and track solo are different
