[OpenLayers-Users] Permalink seems to not update map

[jfranklin]

I've added a permalink control to my map (via map.addControl(new
OpenLayers.Control.Permalink())) as shown in the permalink example on
the openlayers.org website.

However, it seems that when I take a copied permalink URL (after zooming
in a few times etc) and drop it in a different browser, it seems to have
no effect.  I get the default extent/center/zoom level.

The page in question is here:

Any ideas?  And thanks in advance for the help.
