Ah brilliant! Thank you Martin :)

If/when this is replaced, would this bug thread to be referenced? It would 
certainly help with updating the modes affected.

I guess etiquette would dictate that a mode should set these to the maximum of 
the existing value or its own for cases when two modes want control of minimum 
margin width.... is that a case that can arise? I guess it is.....
