Hmm - this would surprise me.  It looks to me that maybe I'm missing 
something about clean up from exceptions.  baybe the std::ifstream lIn( 
lpszPathName ); should be moved outside the try block.  I wouldn't think 
that should be necessary but now that I look at this it might be.  What 
happens when you do this?  Any C++ expert want to opine on this?
