Second Display Closing Problem

I know we have more strategic problems, but I have a funny small problem with closing (set invisible) the second display.
Consider the following simple code:

from visual import *

d1 = display()
d2 = display()

b1 = box(color=(1,0,0), display=d1)
b2 = box(color=(0,0,1), display=d2)

tl = label(text="Which display is selected?")

sd = tl.display

sd.mouse.getclick()
sd.visible = 0


The label text appears on the second display. Upon click, second display should be closed. It does, but then Vpython crashes.

There is no problem with closing the first display.

I am running on 5.50

Am I missing something?
