leaving you with ctrl-alt

So I guess that the application is consuming that very keypress
somehow by communicating with the X server (grab the key(s) in

The application probably also communicates with the X server which
this time is nxagent. So nxagent would probably not pass the grab to
the real X server.

You could try if the coming autograb feature helps here.

But for analysis we'd need the application to see what is doing.

For the records: I think it is nx-libs so we should open an issue
there. But I am not sure if we will be able to fix that at all.
