[erlang-questions] Re: Distel

[Robert Dionne]

Well I spoke too soon about it working now. I re-initialized  
everything and can reproduce your scenario below. So running  
distel:who_calls first gets it going. So you may be right that it's  
an emacs issue. I recently upgraded to Aquamacs 1.7, based on emacs  
22.3.1

I hadn't known this function was available before upgrading to erlang  
R13B

Cheers,

Bob
