[Chameleon] What does chameleon do?

[pxniw pxniw]

Well, I am still Working with Juliens suggestion. And
beleive or not, I got it working with All Navigate
Functions.

Currently what I have is 2 images showing SqlQuery
Image and then other dhtml map image (Which I could
use as KeyMap) . If I click on dhtml map, it navigates
as I clicked the sqlquery image. I have to play around
a bit, so I can hide the dhtml map, so everything is
"userfriendly" navigate.

Still no luck with Labels working ;(
Tomorrow is another day... maybe then.
