Sorry was not 'blaming' duplicate nodes map directly. Unless that is it DOES 
highlight nodes which are at different elevations? In which case it should 
simply not be highlighting them in the first place? Then people would not be 
'trying to correct them' ... If nodes have a different elevation then they 
perhaps should be identified differently if they need to be highlighted?
