Ctrl-C in Windows VNC viewer, Redhat VNC server

I've got a redhat box running VNC server on it. I can connect fine w/ a
Windows viewer and most things work fine. Ctrl-C doesn't seem to
interupt though.

$ stty -a
speed 38400 baud; rows 24; columns 80; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase =
^W;
lnext = ^V; flush = ^O; min = 1; time = 0;

Ctrl-Z works fine, but Ctrl-C is not interrupting any programs. I have
to Ctrl-Z out and then kill the process. Ctrl-C works fine from the
local X server. The Ctrl-C seems to be generating the same ASCII 03
from both the VNC viewer and local X server.

Anyone have any ideas?
