Tried to bind Ctrl-c and to kill-ring-save (i.e. copy) and it *sometimes* doesn't work with mouse!?!? Very confusing

[Chris Seberino]

I like binding Ctrl-c to kill-ring-save (i.e. copy) which is pretty standard in 
many situations....

(global-set-key (kbd "C-c") 'kill-ring-save)

My goal is be able to highlight regions with the mouse and use C-c to copy that 
region for pasting later somewhere else...

It seems to be very flaky.  It seems to *sometimes* work and sometimes not
when I highlight a region with the mouse.

In fact, I was trying to debug and it kept working in lots of different 
situations which was odd.
