I have the same issue on a Mac when connecting to a Linux system. CTRL+Tab does not work. This is a key combination that I use very often and so this significantly impacts my ability to use NoMachine.
I’ve subscribed to the fix mentioned above. Can we ensure the fix is also applied to the Linux server? I don’t know if the problem is on the client or server side and so it could be fine as is if the problem is client side.
I have server version 4.4.1 and player version 4.4.6.
