If you add a custom symbol its added to the font of the list of the symbols 
displayed when you open the symbol picker. When you pick the symbol and go 
back to the mapedit window the graphic for the symbol is out of wack (in the 
map edit window only, in preview its fine). So if 4 was a square before, 
adding a symbol makes it a 5, but if you select 4 it will show the square 
graphic instead of what it should be, and when you select 5 it shows whatever 
the 6 graphic is.

Fairly minor thing, certainly not a show stopper of any kind. Creates the map 
file fine.
