Hi
When you visit the site, http://www.dekoh.com, you will:

1. See a link called "login" on the top-right side of the window. If you do, use this link to login to Dekoh Desktop.
2. Once you are successfully logged in, you will see the link "my desktop" on the top right of the window.
3. Click on this (my desktop) link to install and start Dekoh Desktop.
4. This will display a message, "This will install Dekoh Desktop if not already installed. If you already have Dekoh Desktop installed on this computer it will tak you there. Do you want to continue?". Click OK.
6. When you want to logout of Dekoh Desktop, use the link, "logout".

When click on "my desktop", then:
" Explore what your buddies have shared for you.
" Click here to start installation!

Then:
Dekoh.net
Click here to download plugin
Click here for help
Installation problem? Click here for other way to install

I clicked on "click here to download plugin" BUT there nothing happens!
Then I press right-mouse on it then choose "copy Image Address" and I copied it on terminal :
"http://www.dekoh.com/cas/themes/app/images/bodybg.jpg"
Then I pased that URL on Opera and ALL I see is THE EMPTY DESKTOP (white box with a black thing in the middle !)
