Oh, you are right! But then, wouldn't it be sensible to have the program 
do that for me? Maybe zoom to a certain scale that is related to say the 
size of the bounding box of the layer? So the scale would be different 
for a layer containing global disaster points compared to one containing 
local addresses.
