Ok, I'm now trying to use WinDbg.  I read somewhere to set a breakpoint 
on _main, but how?  First I use the "Open Executable..." command, and 
that works.  I've also set it to download symbols automatically.  So 
far, so good.  Then, if type "bp _main" it says "Bp expression '_main' 
could not be resolved, adding deferred bp", for "bm _main" it says "No 
matching code symbols found, no breakpoints set."

What am I doing wrong?
