The vline.el that I'm using is attached to this email.

Please, check if we are using the same file and patch.

I'm using:

GNU Emacs 23.0.50.2 (i686-pc-linux-gnu, GTK+ Version 2.12.1)
 of 2008-01-12 on debian-hillux

These are the steps I've done:


1. emacs -Q vline.el

2. shrink Emacs until display 27 columns;
    (So you have a lot of long lines)

3. M-x eval-buffer RET

4. M-x vline-mode RET

5. C-n (several, well, you can hold the key pressed)
     It's all right until here.

6. shrink Emacs until display 3 lines;

7. C-n (several, again, you can hold the key pressed)
    Continue all right.


Without the patch, it has some problems.
