Except ....
that my FF
- doesn't display any street names.
- It's slow like hell (My little 3GHz,2MB RAM Machine
is unworkable while displaying these svg-s)
- It takes 20 seconds to render
- It takes 20 seconds to zoom
- It takes 20 seconds to move
And I tried with an IE on an Windows XP.
It only displayed the XML structure and no picture.
... well ...
