Camera.getImage() returns empty frame

[sixtemesseven]

I have a strange error while using your pyhon lib to interface a DMM 42BUC03-ML.

The code seems to work but on some machines the Camera.GetImage() function returns with a all zero array.

I installed the driver, IC Viewer, the thisgrabber dll installer (seperatly, altough it seems included in the Phyton folder as well) .

One pc does work all the time. One pc I had working, then the next morning it would only return black frames during a demo. I tried 5min later and it did work again (with nothing changed...). On another machine I can not get frames no matter what (all Win10 machines).

Is there a way to get some more insight into the thisgrabber dll which the thisgrabber.py accesses? Some debug outputs to analyze or share here?

Then you got no images.
Do you use the camera in trigger mode?
Can you please share some source code, so I can see, how you configure and access the camera?
