You were right. It was my typo error on the "emu" path. I don't think I was 
ever emulating, but I was getting some mixed results. It looks like things are 
clean now. My typo error looked normal. It would probably take me a few more 
days of experimentation to catch it.

I don't think the driver display parameter is an issue now. I did replace 
straight "ansi" with VGA.grd ansi.

Thanks!
