Howdy!  I'm working on a program that is using Exec message ports to do
intertask communications.  I was first using the amiga.lib CreatePort()
and DeletePort() functions.  But there seems to be a problem when I try
do delete the port I've created and used.  The program usually ends, but
then the system is really messed up (i.e., windows get filled with garbage,
or the whole thing just locks up).  I replaced the amiga.lib functions with
my own (following the Exec: manual) and it works fine.  My question is:
Is there something wrong with these functions in amiga.lib (Aztec-C) or is
more being done than allocating a signal and port and both being deleted?

Thanks for any help.

-Brian
