I appreciate everyone's interest in getting this fixed. Unfortunately, I 
don't have on hand a board design that I can send, the particular design 
that I'm having this issue with is for a customer and I don't have the 
liberty to share it.

It looks like Wayne Stambaugh has experienced a similar if not identical 
problem, although I don't think I'm having any DXF export problems. He 
seems ready to send an offending board for debug purposes. Wayne, do you 
think you could send something to Lorenzo and JP Charras?

Lorenzo, I'm not exactly sure what the 'butterfly' is that you mention I 
should produce a summary test with. Can you explain?

Thanks everyone!
Kelton
