Break and suspend problems

[Andrei Zmievski <andrei@xxxxxxxx>]

Hello,

I recently upgraded to RedHat 6.2 and that installed zsh 3.0.7. Now I'm
having problems with Ctrl-C and Ctrl-Z. If I do tar tvf on a large file
for example I can't interrupt with Ctrl-C. Similarly, I can suspend some
programs with Ctrl-Z but not others. Here's my stty -a output if it
helps:

speed 38400 baud; rows 24; columns 165; line = 112;
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;

Any ideas on what might be wrong?
