I experienced the same symptoms, but one should not be so quick to
re-boot.  Always try other things first, like <Ctrl-C> and
<Ctrl-ScrollLock>, etc.  In this case however, these don't help.  The
remedy is a bit more obscure.  Ever think of typing "mode co80" even
though the screen is comatose and you get no response to the
keystrokes?  It worked for me.  Seems Turbo_Prolog QUITs leaving the
system in "Monochrome Monitor" mode or at least not a "Color Monitor"
mode.  (I have not gotten around to contacting Borland about this.)

I use the following batch file (called "TP.BAT") as a workaround:

	PROLOG %1 %2 %3 %4 %5 %6 %7 %8 %9
	MODE CO80
	EXIT

Now you would invoke Turbo_Prolog by typing "TP" instead of "PROLOG".

BTW, NANSI is not the only culprit.  I encountered this problem when I
first started using Turbo_Prolog (FCONSOLE was loaded at the time).  I
tried again using a "bare" system (no CONFIG.SYS and no AUTOEXEC.BAT)
and there was no problem with QUITting.  Everything is fine when
ANSI.SYS is loaded as well.  The above batch file enables one to use
FCONSOLE (and NANSI as well, I assume).

P.S. I would be interested in anyone's reactions to Turbo_Prolog in
     general (actually, the more specific, the better).  If I get a
     significant number of responses, I will summarize and re-post
     to the net.
