[OSM-talk] arbitrary markers on main map

[Shaun McDonald]

You should have only one mlat and mlon  in the url, otherwise there is 
an undefined result. Removing the lat and lon from the url should fix 
the problem.

I usually find that removing the layers can help too, so this gives:

http://openstreetmap.org/?mlat=-36.88887&mlon=174.75006&zoom=15
