Sorry it doesnt seem to work here.  I just did it again at
1815 EST time, see the attached screen capture here.
See jfindu-menu.bmp where you see that I have
selected "do not display CWOP stations" on the MENU page.
Then see jfindu-cw.bmp where you see there
are 30 or more CW stations on the map.

They do not disappear when I make the no-cwop selection.

This does not make any sense to me.  I cannot
think of any map that  does not have a range
from the center to the edge in miles or kilometers
that can be used to give the viewing user an
approximate idea of the size of the actual area 
he is looking at.

As it is, although one can zoom up and down in
jfindu, one never has any clue what actual
area of the world he is looking at until he sees
some geographical clue that he is familiar with. 
 Now for people familiar with an area, this is 
probably not much of a problem.
But it leaves viewers visiting an unfamiliar area
quite clueless as to what size of the world they 
are looking at.

I would suggest placing a legend somewhere on the
map display page that suggests the approximate
range scale in view.  Range being defined as the
approximate distance from the center to the
closest edge. (the fartherest range that still fits
on the map, no matter what the projection).

 You can easily zoom in and out to your heart's desire by
clicking once on the map and using the PageUp and PageDown keys.  The
full table of key commands are shown below the map.
