Multiple Viewports in Vizard, Utilizing keyboard callback

Hi,

I tried to create 4 viewports on the screen at once.
I have the main viewport, and then
3 viewports on the side.

I used a simple keyboard callback function to
turn the viewports on and off.

Below is the code I am using.

Everything works fine up until I press a,s, or d 4 times. After
the fourth press, Vizard will crash.

Is this just sloppy implementation on my part?

Also, the next thing I will be working on when these
viewports stop crashing is making the viewport
lock in on whatever the previous view was.

Can I simply set the
viewpoint of the window
to the main cameras view
and update it every time there
is a keyboard event (which in my
case will only make the viewports
turn on and off).

~~Thanks,

George

def mykeyboard(key):
	view = viz.add(viz.VIEWPOINT)
	if key == 'a':
		window1.visible(viz.TOGGLE) # Hide the window

	elif key == 's':
		window2.visible(viz.TOGGLE) # Hide the window

	elif key == 'd':
		window3.visible(viz.TOGGLE) # Hide the window

viz.add('outersphere.IVE')
viz.add('innersphere.IVE')
viz.add('plane.IVE')

window1 = viz.add(viz.WINDOW)
window1.position(0,1)
window2 = viz.add(viz.WINDOW)
window2.position(0,0.25)
window3 = viz.add(viz.WINDOW)
window3.position(1,0.25)
