[imp] IMP 3.2.1 error Saving attachments

[fran at his.com]

Since upgrading to IMP 3.2.1 (to get rid of and error opening excel files) and 
installing Kronolith, I've got this new error


Saving attachments causes an error:
"You don't have permission to access /horde/imp/download/ on this server."
(it was not occuring with 3.1).
horde is setup to use the default temp dir, and in php.ini, the default value 
is /tmp

I don't see any directory "download" anywhere on the server (which is wy I get 
the error I suppose), but I don't know where this value "/horde/imp/download/" 
is defined in the horde/imp config files.
And also, since the upgrade, .doc (MS word) attached files open in a browser 
window instead of calling MS Word.

Any idea?

Thank you.
