Sounds like a bug.  `M-x report-emacs-bug RET'.

(I assume your Emacs is compiled with GTK+ support on X Window.  Otherwise,
`mouse-2' should do nothing on the scroll bar, AFAIK.)

That last part makes it sound like the only reason you want to do this is
because of the bug mentioned above.

Maybe the modes of those new buffers impose transient-mark mode?  Have you
checked the (local) value of variable `transient-mark-mode' in those buffers
(use C-h v)?

If not, consider filing a separate bug for this.  You should be able to use the
Options menu to turn off t-m mode and then use it to save your changes, and
those changes should be respected in new Emacs sessions.  When you file a bug,
give a step-by-step recipe to reproduce it, starting from emacs -Q.

(It's important to start from emacs -Q.  Otherwise, there might well be
something else from your .emacs or something it loads that is affecting the
behavior.)
