Very easy to get around a Popup if you want the Popup as in a U2U ;)
Just hold the Ctrl Key down as you click on the item that gives a Popup, this will allow that Popup. :(
If you don't use this method it means that you won't be able to access some forms of internet banking as they use Popups too. ;)
Popups are usually disabled by small programs such as Google toolbar and are quite effective, if you are being annoyed by Popups the Google Toolbar is a good solution, just remember to hold down the Ctrl Key when you do need to allow a Popup. :(
