[OSM-newbies] Using map display on slow connection

[Rick Collins]

Some of us are still on dialup with slow transfer rates.  When 
viewing the map display at many of the various web sites, including 
openstreetmap, the map often does not fill incompletely.  At 
informationfreeway.org, for example, some of the tiles will be a 
light blue.  On Google maps text will show in place of some tiles 
saying that "we don't have imagery at this zoom level for this 
region."  I know it does exist since I can often see it, just not 
this time.  I assume that this is a problem where the slow transfer 
rate has caused a timeout of loading that tile.

Is there a way to force reloading of a tile on any of these 
displays?  Reloading the full page often does not help either because 
the same or a different tile will still not be loaded, or because 
reloading the page takes you to the original zoom setting instead of 
the current one.  Any ideas?
