Chose your Windows and then Select Sub-Region and select whatever Region you are trying to capture in the Window.
Where do you find the sub-regions tab?
I'm clicking on windows capture and all that shows up is properties for "windows capture"
exactly thats where you have to get on to. If you want to change a property you have to get into the property option of the specific Source.
Alt+drag the border of the source in the main window is another way to crop.
