Hello, I must say thank you for your work. I always wanted to have monitoring system with extra screen and this software got me going.
Like the title said, I found my sensor panel resetting it's position to 0,0 to my main monitor whenever windows UAC prompt dims my screen,
then it keep lowers the sensor panel each time I trigger UAC prompt.
After I lower the UAC settings to not dim my screen, the problem went away.
I don't know if this is what you need to see the log but here it is anyway.
