[Chameleon] proxy problems..

[Sears, Jeremy]

Hi,
I think Ive narrowed the problem down to our particular flavour of cascading
style sheets. For some reason, one set of styles we are using with the site
in question breaks mapserver, or at least does somthing to prevent it from
drawing on the page. When I subsitute in older style sheets we were using
with this same app some time ago, everything works fine. I dont know what
the problem is specifically, nor am I sure if it is particular to our set-up
or if it is more of a broader compatibility issue.... Im currently looking
into it. Thanks to everyone who has provided assistance.

Jeremy

What did you comment out to make it work?

When viewed from the web, the drawmap URL works?
