[imp] problems with wvHtml and xlhtml

[Marco Maiani]

I have some problems with imp opening word and excel files attached to 
the e-mails. Only pdf files are working right.

On Word when I click on the link I have the following message:

"Il programma per visualizzare questi dati (/usr/bin/wvHtml) non e' 
stato trovato nel sistema." (The software to view these data 
(/usr/bin/wvHtml) wasn't found on the system).

I have the same message with Excel, but the softwares are really on the 
right directory (/usr/bin/wvHtml and /usr/bin/xlhtml ) and the 
mime_prefs.php seems to be right. I read also about my problems at 
wiki.horde.org  but I did't find how to fix it because everything seems ok.

Thanks

Marco
