issue resolved:



I had modified the common-header.inc templates to include our company logo.



The new version of horde/imp had new template files with quite a few 
modifications.



once I put back the originals as came with the distro, sending mail 
worked again.

After having upgraded to IMP 4.2 final, I am not able to compose 
emails. The 'send message' button is not working, nor is the 'save 
draft' button.



I have installed Firebug for Firefox, and the following error comes up 
when I click on 'send message':



"IMP is not defined

uniqSubmit("send_message", click clientX=0, clientY=0)compose.js (line 1)

onclick(click clientX=0, clientY=0)"

(then includes compose.js code)



I changed the compose_popup to 0, and I still get the error, but I 
also get a similar one BEFORE the compose screen comes up:



"IMP is not defined (mailbox.js)

var keyId,startrange=null;function anySelected(){return 
$H(messagelist).keys().d..."



when IMP loads, I get 6 of these, all with different charCodes:



enter_key_trap is not defined

submit_login(keypress charCode=115, keyCode=0)login.php (line 29)

if (typeof e != 'undefined' && !enter_key_trap(e)) {



I'm not sure if these are significant, but thought I'd mention them.
