[imp] Problem with DIMP and Javascript.

[horde at saganew.com.br]

Good day. 

I made a new installation of horde, configured everything correctly,
however, when I click new message, it opens a new window and stands in
Loading ... 

Already checked all the apache logs and horde and not found any
problems. 

Only problem I found was in javascript debug. 

Follows the javascript error in DIMP: 

Uncaught TypeError: Cannot read property 'observe' of null 

Has anyone had the same problem? 

Thanks.
