A bug in upload files button?

Hi friends,

I have a strange issue here. I config the path uploads to images and files but I can upload only using the Resources Browser (this works fine). If I try to use the Send to Server button, nothing happens.

I don't believe that this is a problem with file uploads paths because the resources browsers works well to all files (including large files like 10MB). Also, the "test.html" page works fine. So... is this a bug in the upload function at FCKeditor?

My system is:

FCKeditor version: 2.2 (current release)
Webserver: Apache 2.0.54
OS: Ubuntu Linux 5.04
PHP: 4.4.0-3
Browsers: Internet Explorer 6.0.29 - Firefox 1.5.0.1
(this issue occur in both browsers)

And what I change:

At connectors/php/config.php:
$Config['Enabled'] = true ;
$Config['UserFilesPath'] = URL.'http://application/datafiles/myfolder/';
$Config['UserFilesAbsolutePath'] = '/data/application/datafiles/myfolder/';

At upload/php/config.php:
$Config['Enabled'] = true ;
$Config['UserFilesPath'] = URL.'http://application/datafiles/myfolder/';

I forget anything? I mistake with any thing? Or this is a really bug?

Thanks for any comment.
