multiple windows with different image regions

I'm trying to use a usb webcam to read an image, split the image into three different parts and display each part on an image window on the front panel. So far, I've been successful using IMAQ extract to get the first third of the image to display. When I try to add another extraction and another window, it either displays the same image in both windows or crashes. I'm thinking the camera has trouble displaying two different parts of the video at the same time, but there must be a way around this. Any ideas?

 

The effect I'm going for is like what's displayed on the three screens in this video if that helps any:

Thanks! It was using the top and bottom corner coordinates in the rectangle definition array that was throwing me off.
