Cubase 3rd party plugins all of a sudden lost qwerty input

I do not know if I accidentally click something or not, but all of a sudden - just like that - plugins stop receiving PC keyboard (QWERTY) input, like when I want to set some specific value - it looks like it focuses still on the main Cubase window instead. If I disable ALWAYS ON TOP for the plugin, it partial solve that issue on some of the plugins, but on some it accepts only some letters.

Can anyone tell me why is this? It cannot be that of the ALWAYS ON TOP option for the plugs as it was always like that. So?

Bad plugin?
On-Screen-Keyboard open?

None of that, prolly something temporarily “broken” in the OS, cos the other day (today) all works again just fine…damn Windows! :slight_smile:
