gnus-cited-lines-visible and scrolling

Hi,

I use Gnus and have this in my customized variables:

 '(gnus-cited-lines-visible (quote (0 . 3)))

I'm in the summary buffer (see attachment) and cursor is on the mail which
is displayed in the article buffer. There is [+] sign (an author of this
mail is not able to cite properly :-)). I;d like to see the end of the
actual mail - so I must press space, I did it, nothing happened. I did it
again, nothing happend again...

This is probably Gnus's fault so I CC: it to ding@.

Gerd,

I think this problem is the same one I sent you email about titled
`problem with move_it_vertically and invisible lines' --

Don't know.  Problems of this sort were previously caused by
pos-visible-in-window-p in gnus-article-next-page, for example.

Pavel, could you please send me a mail which shows this problem?

Perhaps in Pavel's case there's a different cause, but I've debugged an
*identical* situation in gdb, and there the behavior was due to the
problem with move_it_vertically that I described my earlier email.
