I updated to the latest version today, this also happened on the previous version as well. All the lateset win7 updates, and .NET updates.
Can connect and run EZB no problems, can connect to the drone without issue, enable the camera, still fine live video no problem, enable color tracking, still no issue.
put a red target in front of the camera, see the blue tracking square, then the circle of death mouse pointer and a screen refresh with (Not reponding). No more EZB need to kill it off and restart?
Tried various USB ports for both the wifi and bluetooth (all work the same, no change) tried various com ports for the bluetooth connection. Removed the EZB bluetooth device and re-deiscovered and installed it. Went back to .NET 3.5 same problem. Let the system update back to .NET 4 still same issue.
Not sure what else to try
