Hello snejok!
And I noticed small regression in 4.1: there is no EXIT button on screen that appears on session end (see attachments). I want to say that very difficult to close NX4.1 windows if there is no window decorations in my environment (embedded systems). NX3.5 was more ready for embedding.
This is still working, but you’ve to start the player with the ‘–exit’ command line option, e.g. nxplayer –session file.nxs –exit
