I am using NX clinet-3.5.0-7 version running on ubuntu 12.04. I am trying to use Alt+Tab key to switch between different terminals on my NX client but I am unable to do so. When ever I use Alt+Tab, it switches the different panels open on my Ubuntu 12.04 instead. I tried to follow this link but that didn't help as there is no "Grab the keyboard when the client has focus" option in Advance Tab.
I also tried link but nothing comes out.
