Hello,

After (set (make-local-variable 'track-mouse) t), when I click anywhere in
the buffer, track-mouse will be reset to nil.

Emacs 24.5 didn't do that. It breaks a tooltip system I have for coding in
C++ : I alternate between typing, clicking and hovering over variables to
get tooltips. I cannot debug track-mouse because it is in the C layer of
Emacs, not in lisp.

Anyone can help ?
Thanks,
Vincent
