hi Mario, 

yes, a typo - I had written the shortend memorizied output (Maxima is running on my other
notebook) and '..' meaning 'and so on'.

I have installed 5.11 once again from scratch,
but the same phenomenon occurs: no graph waiting on screen, only a very short 'flash of a
graph'.

No, it doesn't work for me - same effect: only 'flashing graph'.

Q: I have only substitued draw.lisp(1.6) with draw.lisp(1.7)
   is it sufficient only to exchange this file?
   Maybe, are there changes involved in other files too?
