In order for someone to help you capture co-ords on an area of a hidden window, they would first need to know how you are capturing the full hidden window.

Dont be shy, post your code.

this is my code. it would capture hidden window but can't do with minimize window

i don't know why but sometime it can capture a specific coordinate, sometime it don't work
