(still haven't managed to set up imap yet)

if you click on the "attach file" text box to try and select a file to attach yo your email message , you get the following in a new web page:

!ERROR Notice: get_var(var = action, method = Array ( [0] => POST ) , default = ) has been replaced by phpgw::get_var(var, data_type, method, default), please update your code in /path/to/phpgroupware/phpgwapi/inc/common_functions.inc.php at line 163
 
!ERROR Notice: get_var(var = delete, method = Array ( [0] => POST ) , default = ) has been replaced by phpgw::get_var(var, data_type, method, default), please update your code in /path/to/phpgroupware/phpgwapi/inc/common_functions.inc.php at line 163
 
!ERROR Notice: Undefined variable: uploaddir in /path/to/phpgroupware/email/inc/class.boattach_file.inc.php at line 300
 
 Fatal error: Call to a member function dir() on a non-object in /home/jason/website/phpgroupware/email/inc/class.boattach_file.inc.php on line 301

(there's no dialog here to select a file at all , so at the moment you can't attach files if you wanted to)

Note that clicking on what appears to be a text box to bring up a dialog doesn't fit so well with how your average user would expect this to work.  I'd expect the text box to just be a text box , with a button next to it that you click on to show that dialog.
