NHANES Dietary Web Tutorial

Technical and Software Requirements

How to Allow Pop-up Windows

You or your system administrator may have installed and turned on pop-up blocking software on your computer.  Although this software typically blocks unwanted pop-up advertisements, it can also block necessary content presented in pop-up windows. In the case of the NHANES web tutorial, it can block the “Key Concepts” and “How to” text, the animated demonstrations, and the other important information.  When many pop-up blockers block a pop-up window, they display a yellow bar below the Address field containing a message similar to the following: "Pop-up blocked. To see this pop-up or additional options, click here ..."

Microsoft Internet Explorer

To allow pop-ups through Internet Explorer's pop-up blocking feature, which came with the Windows XP Service Pack 2:

1.      Click the yellow bar described above.  A context menu will appear. (See screenshot below.)

2 .       Select “Always Allow Pop-ups from This Site.” A dialog box appears asking "Would you like to allow pop-ups from 'www.cdc.gov'?". (See screenshot below.)

3. Click the Yes button. The page then refreshes - it may appear as if the page 'blinked' - and the yellow bar disappears.

4. You can now click the link that was blocked earlier, and the pop-up window will open. Other pop-up windows in the tutorial and on the CDC site will now open properly as well.

 

For more information and detailed instructions on how to use the pop-up blocker, please view the pop-up blocker help available on Microsoft's website - http://www.microsoft.com/windowsxp/using/web/sp2_popupblocker.mspx

 

 

Mozilla Firefox

In initial tests, the Mozilla Firefox browser always allowed the tutorial's pop-up windows, regardless of settings. However, if your version of the browser blocks the tutorial pop-up windows, go through the following steps.

1.      Go to Tools→Options, and then click the Content tab.

2.      Click the button labeled "Allowed Sites," next to the line labeled "Block Pop-up Windows."

3.      Enter www.cdc.gov in the "Address of Web Site" field. (See screenshot below.)

4.      Click the "Allow" button. (See screenshot below.)

5.      Click the "Close" button to exit the dialog box. (See screenshot below.)

Additional pop-up blocking software packages are available and it is possible to install more than one (e.g. XP's pop-up blocker and the Yahoo! Toolbar pop-up blocker). You will need to consult the software's Help section for additional assistance on how to allow pop-ups from the NHANES web tutorial. Below, are listed some of the more common pop-up blockers and links to their help sections.
