Rob,
I'd suggest adding this to the bug database as a feature request so
it doesn't get lost on the list. I know the bug database is getting
bigger all the time, but some of the bugs are actually getting fixed
and Martin is doing a great job implementing some of the feature
requests for the UI.
Feedback can be added to the bug database as well and if you
implement some code for it, you can then refer to the bug # when you
post any code.

Ok, saw that now. I usually do not start DX from a terminal, but with a
preset-command in my window manager (Xfce in my case) and stdout is rather
hidden that way. Also, what about following:
start vpe in terminal window (dx -edit), make a new network without saving it
and then press ctrl-C (SIGINT) in the terminal. Boom, vpe gone. No message and
nothing saved. Everthing gone!
Since SIGINT is not a fatal interrupt, this is not an emergency. The
vpe, or dx
in general, should pop up a window whether the user indeed wants to
quit without
saving the data. If the anwswer is "no", vpe and dx should continue without
quiting. This holds not only for SIGINT, but for several other
non-fatal interrupts.
I haven't looked into detail, but briefly noticed that signal
catching is scattered
over a whole bunch of files in src/exec/dpexec src/exec/hwrender
src/exec/libdx etc.
It uses "signal(SIGno, handler)" style, but according to the GNU
glibc library this
is not an optimum way of platform independent signal catching:
