This message is posted when the user releases the right mouse button while the cursor is located within the client area of a window. If another window has not captured the mouse, the OS posts the message to the window beneath the cursor. If another window has captured the mouse, the OS posts the message to the window that has captured the mouse.
A window receives this message through the WindowProc function for the window.
