PopOops is a small and easy to use program that blocks popup windows in Internet Explorer. It runs in system tray and optionally plays sound and/or shows balloon tooltip (Windows 2K/Me/XP only) every time popup is blocked. If blocking caused a script error message box, it will be automatically closed.

PopOops is OSI Certified Open Source Software and is distributed under GNU General Public License (GPL).

Program requires Visual C, Visual Basic run-time files and Internet Explorer 5.0 or later
