[horde] Can't upload attachments to Imp

[Daniel A. Ramaley]

Hello. I am running Horde 3.0.7 with Imp 4.0.4 on a Linux server with 
Apache 2.0.52 and PHP 4.3.9. I can send messages just fine, except if i 
try to include an attachment. To attach a file, i scroll to the bottom 
of the compose page, hit "Browse...", select a file from the open 
dialog, then hit "Attach" back in the compose page. With Firefox (on 
either Windows or Linux), hitting Attach does nothing. With Internet 
Explorer on Windows when i hit Attach, the status bar displays "Error 
on page." Any ideas? I'm not using a proxy that modifies content, and 
javascript is enabled in the browsers that i've tested.
