Step 1. Before you start to capture, you need to decide whether you want to capoture the whole screen on the desktop, or just one window object, or an item with your own mouse selection?

• Desktop Mode --- Capture whole desktop screen for you
• Window Mode --- Capture objects within one window of the desktop
• Region Mode --- Capture items inside a rectangle region, which will be selected by you

Once you have decided your capturing mode, then press the corresponding button, if you specify to capture the whole desktop, the captured window will be shown, if you specify to capture window object or region, the main window will hide away, and you need to select the window object or define your rectangle region.

finally you will see the main window again, together with a captured image.
