Control key (windows) not working

Dorico
1

Suddenly my Control key stopped working, I think after updating to 6.1, but I’m not sure. Works fine in other programs.

Thanks, robert

UPDATE: It’s actually not the control key that is not working, control+s works fine. It’s, for instance, control+8 that is not working, although it shows up in the key commands.

I checked this in Dorico 5, and there Contr. 8, works perfectly. So must be somethingin Version 6.1?

EDIT: after some more investigation, this seems to be connected to my Corsair keyboard. Maybe I unwittingly changed a profile for this keyboard.
