I am not sure what could be causing the software to stall, but here is the description for the Edge Detection Test from Toolbox:
Edge Detection Test - This test verifies that edges can be detected in an image captured from a Web camera
Depending on the lighting and what is in the field of view, it is possible that the camera is simply unable to pick out any edges. If not, then there is likely another issue occurring in the background (based on the lockup you are seeing, I would guess that there is more to this issue than just a poor backdrop for the test).
If you don't mind, we would like to take a closer look at this issue, and see if we can determine what is causing both issues. I will be sending you a PM shortly with instructions to obtain the logs that we need, and where to send the files.
We would greatly appreciate your assistance, and I'm sorry that I don't have a quick answer for you.
Thanks in advance,
Kris
P.S. Why do you seem to keep having these interesting Toolbox problems.....
(at least it's been a while)
