I have three important questions of which one is actually an Emacs question 
or better an Ange-ftp question.

1) I have an elisp-code file (sml-mode) which is written with Epoch 3.x in
   mind. In these versions buttons where still in use. 
   In sml-mode.el the author makes 
   heavily use of attributes of buttons.el. What I actually 
   want to know is how I can use
   functions like reserved-attributes under Epoch 4.2. I can't find
   these functions in the new buttons.el (which only maps certain buttons
   functions on zone functions).

2) I'm trying to use rmail in conjunction with ange-ftp so what I do
   is 
	(setq rmail-spool-directory "/dirkd@neptunus:/usr/spool/mail")
        (setq rmail-primary-inbox-list '("/dirkd@neptunus:/usr/spool/mail/dirkd"
					 "~/mbox"))

   so when I want to read my new mail ange-ftp accesses my mail spool files
   on the other computer (neptunus). While reading mail I can't access my
   newly arrived mail because ange-ftp already has one subprocess pending.
   So pushing 'g' hasn't got the right effect (Emacs or better
   Epoch tells there is no new mail for me, without actually checking the
   mail box on neptunus). When I kill the ange-ftp ftp process or the
   ange-ftp buffer that was created for doing the actual ftp job everything
   seems to work properly. Any suggestion how I can patch this problem 
   without rehacking the rmail elisp file, because I know how I can do that.  

3) Is it worth to wait for Epoch based on 18.59 because I'm planning to 
   reinstall Epoch (recompile it).
