I've seen failure to load before, on InformationFreeway too... but in each
case it's been due to failing to download the large openlayers javascript
file due to poor connectivity (large packet loss) a few refreshes can help
get it to eventually download then it seem to stay cached and works for a
while... I'd guess that the person reporting this has some sort of
connectivity issue or something else blocking the javascript such as a
filtering proxy or worse as far as having a chance of fixing it, an ISP
caching a broken copy of the openlayers javascript...

I have noticed issues with Firefox 3 on Windows and the slippy maps
though... they load fine but dragging the map occaisionally takes the map
decorations with it... found it's seems slightly more reproducable if the
find bar is open at the bottom of the screen and you are panning north
(dragging mouse from top to bottom) and the mouse goes into the find bar
while the button is still down, but then, it's still so variable happening
maybe once in 20+ full screen drags... when it happens the decorations move
about a tile's width in whichever direction you are moving the map...
