US Patent 7100122 Limiting unsolicited browser windows

A system, method, and program controls the occurrence of unsolicited browser windows by enabling a user to specify a maximum depth of a window that can be opened. Before opening a new window, the browser determines the window depth in relation to the specified depth. If the new window to be opened has a given depth in relation to the specified setting which allows the new window to be opened, the window will be opened. If the new window to be opened has a given depth in relation to the specified setting which does not allow the new window to be opened, the window will not be opened. Furthermore, the browser prevents a new window from being opened from a current window if the current window is being closed.
