If you are on Win32, post the output from Perl -V and I'll see if I can isolate the difference.

If you are on some flavour of *nix, then maybe ^C doesn't generate a SIGINT? You'll have to talk to someone with knowledge of your platform to resolve this issue.

I should add that using an interupt handler this way is not really an "architected" solution, just a simple mechanism that allowed me to produce a reasonably clean demonstration without getting into the nitty gritty of a full fledged application.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
