Thanks Allan and Michael!  I re-set everything up from scratch using  
fresh downloads and got it all working. Will post the exact steps in  
case it's useful to someone else in another msg.

Yes, definitely. I've got a few typos and little things for  
DKSimpleDXF and DXFReader...

Excellentl! I'm wanting to import DXFs with INSERTs, and just this  
afternoon fleshed out a BBDXFInsertEntity.m/h, following the style and  
HeaderDoc stuff in the existing parsers classes. Then added INSERT  
support to DKSimpleDXF, and it works - at least as far parsing the  
inserted BLOCK names, insertion points, rotation angle, scaling  
factors and extrusion directions, etc.

But of course it needs to reference the actual BLOCKs to do anything  
useful. Would be happy to send you the diffs, and you can see what you  
think. There were a couple questions that came up that I'd like to ask  
you, but will take those off list.
