Hi Dave,

thanks for sharing this with us. I use mainly IE 6.0. I am even amazed how 
much of the functionality works in Opera 7.10, exceot for the zoom-in box 
(big red panel in map).

I do have some questions about it though:

* How much time does it take an average developer, familiar with Chameleon, 
to build this kind of site?

* I see the key map, which is unchanged in extent during zoom actions, is 
refreshed all the time. Is it cached at the serverside or created all the 

* Is there a way with Chameleon to move layers up and down? This is not so 
important for your demo with mostly point symbols.

* Are all the legend images prepared at the server-side, i.e. not 

* Is there a reason why Chameleon does not use frames? Would it require a 
lot of rebuilding?

* What worries me a bit is the performance, is it due to your server 
environment or due to Chameleon? I see now after testing in Opera that the 
average download speed I get from your server is only 15-20 KB/s, with lows 
in the 5 KB/s, and highs in the 40 KB/s.

* When I use the Quick view dropdown, I sometimes get a Javascript error: 
invalid syntax, line 690, and then a really big URL which seems to have 
returns after the coordinates (so I see KEYMAP_EXTENTS_MAXX=-on one line, 
and the actual X value on the next line of the details panel of the 
javascript error).
I sometimes get the same error when selecting layers and updating the map. 
After this error almost nothing works anymore. I could not generate this 
error using Opera.

Best regards,
