Tait. Please confirm whether your operation works well on windows terminal.

I suspect that the change on 2014-01-04 is related to that you pointed out.
I have aware the phenomenon that all .dem on wxt terminal on windows does not work correctly. Shigeharu Takeno also pointed out that point in the private mail to me.

The change below perhaps related to the phenomena that you have met.

2014-01-04  Bastian Maerkisch  <bma...@we...>

	* src/win/wcommon.h src/win/wgdiplus.cpp|h src/win/wgnuplib.h
	src/win/wgraph.c src/win/resourc.h term/win.trm:  New (optional)
	variant of the windows terminal backend which draws using the GDI+ API
	whenever possible. This is much faster in some cases than the old
	backend which switches between GDI and GDI+ to support antialiasing
	and RGBA colors. Images are drawn using GDI since GDI+ always uses some
	sort of interpolation when scaling images. Enhanced text is currently
	still drawn using GDI. Adjacent polygons of the same color are merged
	in order to avoid "seams" between them caused by antialiasing. See also
	Bug #1096.

	* src/term_api.h src/graphics (plot_image_or_update_axes):  Wrap
	the fallback image output with term->layer() commands using
	TERM_LAYER_BEGIN_IMAGE and TERM_LAYER_END_IMAGE. This can be
	used by terminals to optimize output.

	* src/win/wgraph.c (drawgraph):  Move GDI image drawing code from
	drawgraph() to a new routine draw_image().

	* src/command.c src/fit.c|h src/plot.c|h src/term.c src/win/wgraph.c 
	src/win/winmain.c src/win/wtext.c term/win.trm:  Handle Ctrl-C
	asynchronously on Windows (GUI and console mode). This is done by
	setting ctrlc_flag and testing it in check_for_mouse_event(). Thus,
	scripts etc. can now finally be interrupted by pressing Ctrl-C in
	console mode gnuplot or Ctrl-Break in wgnuplot.

	* src/win/winmain.c (ConsoleGetch):  Remap Shift-Tab key-code in
	console mode, too.

***********************************************************************
The above change solves the CTRL+C issue on gnuplot on windows for a long term.
The change seems to be well on windows terminal but not be well on wxt terminal.

To confirm my assumption, I have to downgrade the cvs source but I have not tried yet.  

Please give me a little bit time to confirm that the change above is an origin of the fault on the wxt terminal.
