Thanks.

On an MS-Windows terminal I don't see this problem, so maybe there's
more here than meets the eye?

Anyway, why do you call posn-at-point with first argument nil?  I
don't think the position of point in that window is at all relevant,
is it?  Should we perhaps use the position derived from mouse-position
instead?

Jared, any comments to this patch?
