Still seeing what I said above: "When the cursor shows as <=> I can also
drag the border." You could try one of the following:
(1) Check whether setting the right-divider frame parameter to 1 suffers
from the same problem.
(2) Try putting `coordinates-in-window-p' in a loop where you simulate
(by incrementing the car of the first argument) the course of the
mouse and display the return value via a message.
(3) In window.c DEFVAR_LISP a new variable, in coordinates_in_window set
that variable to the value coordinates_in_window is about to return,
display the value of that variable in the modeline, and then move
the mouse to find out what it reports.

Hmmm... on 2013-11-30 I have
* xterm.h (struct x_output): Add vertical_drag_cursor.
