    Every so often something seems to “stick” in the connection, and trying to use the mouse scroll wheel results in Chrome changing it’s zoom. Also input seems to become as if the “CTRL” key is stuck on and you end up multi-line selecting. The only fix is to disconnect the session and reconnect. Everything is at the latest version.


    Hi, We are aware of a similar behaviour that another user has reported, although we are not able to reproduce in our own environments. Please confirm the Linux Mint version and desktop environment (Mate, XFCE?).

    Check your inbox from us 🙂 We’ve sent you a test package


    Did you get a chance to test the package we sent?  🙂


    I’m afraid I haven’t. But it’s still occurring from time to time. It’s definitely some process “stealing” the “ctrl+” input and not releasing it.

    Workaround is to close the NoMachine window (not session, for a clue) and reconnect. Since I have a workaround I can live with the bug. However YMMV.


    The link we sent in the email to you to download is for a package that contains a patch. We were interested in knowing if it fixes the issue completely. If you get a chance to test it, please do 🙂
