gnuplot.exe hangs instead of exiting on Windows 7

[Peter J. <pet...@gm...>]

Dear list,

I've downloaded the latest gnuplot 4.5 CVS build from Tatsuro
Matsuoka's site ( http://www.tatsuromatsuoka.com/gnuplot/Eng/winbin/
).

The console executable gnuplot.exe displays a strange behavior:
instead on exiting, it hangs.
If I start it from the console then type "exit", it doesn't return to
the command line.
Even worse, it also hangs when I invoke it as "gnuplot.exe -V".
(That's how I noticed this: one of my applications that uses gnuplot
checks for its presence and up-to-date-ness with gnuplot -V, and
because of this, it appeared to hang on startup. And I spent a few
confused minutes trying to debug my application before realizing that
gnuplot's at fault.)
