[erlang-questions] erlang 21

[Sam Overdorf]

I'm running windows 7 professional.

It works fine with otp-20 and older versions (I still use 20.3) so
something has been changed..
if I run "erl +Bc" then control-c works just fine.
Is there a configuration file for :"erl" that I can add this flag to
to make it work the old way?
I use control-c all of the time.

Thanks,
Sam
