One keyboard input won't type but the other does!
I have 2 keyboard inputs set up on my mac, one is English, the other is Vietnamese.
The English keyboard works just fine, all keys respond, which is why I presume this has nothing to do with the physical keyboard, it's something with the programing or software, wev ...
But as soon as I switch to the Vietnamese keyboard, I can't type anymore, not any key, not even the space bar.
However I do have Stickey keys enabled, so I can tell the function keys, command, control, options, ... are still working, likewise, if I use the function keys AND the rest of the keyboard, it would still respond. But not when typing normally.
Any idea please?
