[Chameleon] Re: [OTT_OSGEO] chamelon-GRASS application site with URL

[Massimiliano Cannata]

Hi Ken,
I tested the site with IE version 6, but I didn't get any errors.. which 
version are you using?
For further information on the back processes, I will set up a web page 
with all instructions and procedures done for the demo realization.

I will inform you when all those information will on-line (for the end 
of October I guess).

Thanks for the feed back.

Maxi
