Well, this opens a new - immediately closing - terminal, with octave-gui.exe 
complaining: 'unrecognized option '--no-gui-libs''.
I tried '--no-gui' instead. This results in an empty octave-cli.exe terminal, 
freezing...
My graphics card is Nvidia Quadro K600.

PS: Tatsuro, I really appreciate your help, but on the other hand I don't want 
to waste your precious time. As - for now - I haven't got any 'hard' reason to 
use 4.0.0 (just the attraction of the new version), I could continue using 
3.8.2 without any difficulty. So feel free to stop at this point, especially as 
it seems that I'm the only user with this kind of problem.
