Two motives of annoyance

[renaud at olgiati.fr]

I am installing pclinuxos-xfce on a new laptop, which will in the
future replace my desktop box.

There are two things I find very annoying in the new set-up, and while
I remember solving those problems many years ago on the desk box I
cannot remember how I did it :

When I move a window to the top of the screen it automatically expands
to occupy the full screen. Can this behaviour be killed ?

Using the mouse cursor on the side-bar of a window (not ON the side
bar cursor) to move up or down in the display becomes unmanageable when
the window displays a content of several thousands lines. How will I
prevent this "acceleration" from raising my blood pressure ?

(Note to self: write the solutions in the Cook Book)

With grateful thanks in advance, and best Xmas and New Year wishes from

IBM 1620 fifty years ago)
