No idea. I guess I learned it from a 'smart one'. I would not be 
surprised if that was Sam Benge. But others have used the trick too I am 
convinced.

Now you ask too much ;-) A learned one like William Pokorny may know...

This is one of those cases where DFP do not help I am afraid. I do not 
know th mechanism but it works. Same as my laptop: no idea how it 
functions... ;-)

I am not a fan of this... The first would be a possibility... hmm, I 
have to think about this a bit. For instance, Map1 /never/ should have 
any filter or transmit info.

They are free to try, but have to play by my rules ;-) For different 
reasons, I have restricted the use of transmit to the veins where 
filters are not allowed and imo, are not recommended.

Veins, btw, is still an issue of course.
