Greetings.


  Actually, the problem does not occur in an editor like vim, but when at the bash
  prompt.  What you explained is right, but it is not the problem I suffer from.  I
  am at my bash prompt, run a command like ls -l, then scroll up the window and
  behold, the data shown is not that of the beginning of the ls -l command.

  There seams to be serious problem with the buffer/scrolling routines of rxvt.


Thanks for replying.
Hans

Not exactly.  You see, some programs (like less and vi) actually use a
secondary display buffer.  If you use the arrow keys, you can tell less
(or vi) to change what portion of the file they display in that
one-screenfull-tall buffer.  However, if you use the scroll bar, you
then see the primary buffer contents.

That is, less/vim will always ONLY control ONE screenful of data.  If
you scroll OUT of that screenful, then you see .... bash?

This behavior is what allows bash(?) to restore the previous "bash"
display after you exit vi or less.

Summary: not a bug.

I use rxvt exclusively, in both X and native modes.  I've never seen this.
