[imp] Attachments widget missing

[Otto Stolz]

Hello,

currently, I am trying my luck with Horde 3.1.2 and Imp H3 4.1.2.

In the message composition window, there is no possibility
to specify an attachment.

Though the help info says:
> Message Composition: Options
...
> Click "Attachments" to go to the bottom of the page
> where you can attach files to this message.
there is no "Attachments" Button in the options field,
nor any provision to attach anything, at the bottom of
the page.

Most probably, a configuration error, but then I do not
understand how to configure Imp 4 for allowing attachments.

I want the attachment to be uploaded to the PHP temporary
storage, and then appended to the respective message when
it is sent. (This same scheme works well for us under
Imp 3.2.2.)

Particular questions:
- What may be wrong with my configuration (cf. infra)?
- What is a VFS, and in particular the Horde VFS?
- What does Imp when you allow the users to send
   attachments as links, particularly, where is the
   attachment stored, and for how long?

Thanks, in advance, for any hint,
   Otto Stolz

Note: I have also tried
   $conf['compose']['use_vfs'] = true;
, to no avail.
