Can it be that you clicked “Don’t show this message again”?
Yes, of course I clicked on “Don’t show again” in every screen 😉 but question is, in version 4.0 I was always asked about muting the remote desktop EVEN after checking such box 😕 What do I mean? For v4.0:
Open Nomachine Enterprise Client.
Click (once) the session you wanted to open.
Click on Connect button.
Confirm that “Don’t show again” is already checked, however you were asked about muting remote sound.
Now with 4.1 is:
Open Nomachine Enterprise Client.
Double click the session I want to open.
So I went from three clicks in three differents screens to a double click in a single screen 🙂 Couldn’t be much happier – I just need the free version but I’ll buy a subscription anyway to support you!!
