[imp] DIMP - Actions that opens in a new window brings the login screen

[Marc Stiebich]

Hi all,

im using Horde Groupware Webmail Edition 1.1-RC1 
<ftp://ftp.horde.org/pub/horde-webmail/horde-webmail-1.1-rc1.tar.gz>. 
Whenever I compose
a new mail, forwarding mail, or any action that opens in a new window,
a new login screen is opened in the new  window. With the other Applications
i didn't have this problem. I searched the mailing list archive for 
similar errors and found
a post with the same error:
http://www.nabble.com/Problem-retaining-login-info-for-new-windows-td13688199.html
But i did not think that this is a cookie problem. In the 
config/conf.php the cookie option is turned off:
$conf['session']['use_only_cookies'] = false;
$conf['cookie']['path'] = 'webmail'; (webmail is the directory where 
horde is installed)

Is there a additional cookie Option for Dimp?

Thanks for the help!
