Somehow this sounds familiar! Can you provide what configuration
change you made prior to this behaviour?

For control characters, check the output of "stty -a". Here is
an example where Ctrl+C acts as intended:

	% stty -a
	[...]
	cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
	        eol2 = <undef>; erase = ^H; erase2 = ^H; intr = ^C; kill = ^U;
        	lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q;
	        status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W;

Where does ^C appear in your output?

The shell also exits on "end of input", which is ^D (eof) which
can be prevented by "set ignoreeof".

Changes to /etc/csh.cshrc or ~/.cshrc?

Try this:

	% stty intr ^C kill ^U
