You will have to disable your ad blocker - at least for now, to see the ad gallery. If you want to see your ad appear when it goes online you will have to leave it off. You can leave the pop-up block enabled and Ctrl click to override it. You might have to close and re-open your browser if your display does not change.Norton Internet Security goes a bit too far with the AD BLOCK option. It removes any graphic or picture that has the word banner, banr or any thing close in it's name. It removes any graphic that is the same size or even close to the same size as an ad banner.
Windows XP Service Pack 2 with the newest Internet Explorer 6 has its own pop-up blocker. It does not include an ad blocker, but it seems to be doing the job of blocking unwanted things well enough without going overboard.
If it was not for harmless ad banners every site would be a pay site - a web resembling cable TV.
