scrollbar issues

[Stephan Hennig]

Actions:
Either load a text file with more lines than fit into a window by typing
 'C-x C-f file RET' or drag a file onto Emacs. Then scroll down and up
using the window's scrollbar.

Symptoms:
(i) While dragging the scrollbar and scrolling down slowly the window
content wobbles vertically. This can be best seen when reaching the end
of the file.

(ii) When dragging to the end of a file and releasing the scrollbar the
size of the scrollbar changes.

(iii) Then clicking on the scrollbar causes the bar to shift up every
time you click.

(iv) This bug seems to interfere with AUCTeX. Dragging the scrollbar to
the end of a window does not move to the end of a file but one or two
lines above the last line. You have to click on the down botton below
the scrollbar to visit the last line (or use the keyboard). This
item (iv) seem only to appear with tex files (AUCTeX is installed on
my Emacs), but not with other files.

Stephan Hennig
