The easiest way is to use a different combination, like
C-S-drag-mouse-1.

Another easy way is to remove the S-mouse-1 key binding.

If you don't want to do either of those two, you will have to rebind
S-mouse-1 to your function that either invokes the pop-up menu or does
the rectangular selection, depending on whether it gets a click or a
drag event.
