OpenCV in WorldViz

[sircedric4]

I just got finished trying the capture-cam.py example and got a runtime error. When I ran it, it first prompted me to select a web camera and then when it tried to run it gave the following error:

Microsoft Visual C++ Runtime Library
Runtime Error!

Program: C:\program files\WorldViz\Vizard31\bin\winviz.exe

This application has requested the Runtime to terminate it in an unusual way.  Please contact the application's support team for more information.

I would like to marry the capturing of a video camera with the square detection of squares.py. Does anyone know what runtime error it is running into. It looks like it is getting hung up on:

# get size of the frame
    frame_size = cv.cvGetSize (frame)
