I couldn't find anything wrong with the code so I deleted my source code 
and started over in the developer's guide.  One thing I hadn't done 
before was change the config.nmake to use the 2005EE compiler instead of 
MSVC6.  Now I can capture and open files :)

One problem remains with name lookup - do you have that enabled when 
doing a msvc2005ee build?  It's crashing at addr_resolv.c in the 
add_ipv4_name() function where it performs this: strncpy(tp->name, name, 
MAXNAMELEN).  Name is an invalid pointer when it crashes after opening 
or capturing 10-30 frames or so even though adns is returning adns_s_ok 
in the previous call (host_name_lookup_process).

Can you duplicate this problem?  I can work on it further, but I wanted 
to make sure it isn't just a problem with my setup first.


Thanks,
  Steve
