The current spacebar is an operation which works well on "single-user" OS/2, 
Windows, and Linux. In the latter, there are many X11 window managers that 
can be set up into a dozen of behaviours, and you can set them up so the 
current spacebar operation is canceled by the window manager. But then it is 
not the private problem of gnuplot.

If you do some other tricks with X11 (logging into other servers, tunnelling 
your X11 protocol), then it may not work, as you have noticed.
Actually ... I've just tried to ssh' -X to our server from Konsole, run 
xterm, run gnuplot, plot x, spacebar, and gnuplot pops up! So it should work 
also for you, why not?

In all my environments it was always doing both...

OK with me, but let those chars to be "bind" by default.

In recent versions of KDE, you must set "control center => windows behaviour 
=> advanced => protection level against stealing (??? or somehow like that) 
=> None". This info should probably go into "help mouse".


In summary, there are two ways what to do:
1. No major changes
    wxterminal copies the raising code from gclient, gplt_x11 and wgraph,
    or
    the code is moved into mousecmn.c and to be called from the above sources

2. Major changes
    Let 'q' and ' ' be "bind"able. Needs routines raise_gnuplot_console and
    term->quit_window. This would need the new API for interactive terminals.


If somebody wants to improve windows changes in some X11 combinations (as I 
did for KDE, for example), he can contribute it to the appropriate place of 
code, independently of the above ways.
