R help - Jun 2000 - ess

i am using  r 1.1.0 and ess 5.1.13
on win2k (with an amd k7).
things behave strangely.

i can start r with
M-x R
and i can give a command
the command will be executed and i will get the answer,
but i will not get a prompt for entering the next command in most cases.

when i do graphics command, things are even more surprising.
then i get a prompt,
but somtimes the graphics window cannot be brought into the foreground.
 
any experiences or strategies?

erich

  This works for me. Have you a non standard R prompt, i.e., 
  different from '>'? If I remember, but I am not an expert
  in ESS internals, ESS relays on the prompt to find the end
  of the previous command output.

  Does the graphic window exist? You can use 'dev.list()' to
  check for this. Reason of the question: surely there is a long 
  standing bug in NTEmacs which makes NTEmacs to eat some  'map on
  the screen event' for a sub-process. This is replicable
  with a application which simply calls  MessageBox and then dies
  (the MessageBox is never shown!!). Brian and I tried to overcome
  this bug simply replicating the event (the two show(xd->gawin)
  in src/gnuwin32/devga.c:setupScreenDevice). Then I didn't have
  problems but I don't use too much ESS under Windows.
