I am running version 18.104.22.168 on a Windows 8 machine. I have been careful to run it only at night in the summer, but run it full time in the (Canadian) winter. Lately I noticed that my dome heater is not working as it no longer melts the snow and barely clears a small “hole” in the center. I cycled the camera connection and 12V feed but no change. The control software indicates that it is active but the results show otherwise. Is there any software fix I can try or do I have to send it for repair. Here is an image taken at -6C.
