You or your system administrator may have installed and turned on pop-up blocking software on your computer. While 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 animated demonstrations and viewing the Tutorial Variable list, animations, quiz and homework activities. When many pop-up blockers block a pop-up window, they display a yellow bar with a message like "Pop-up blocked. To see this pop-up or additional options, click here ..." just below the Address field on your browser, as pictured below. This picture is from Microsoft Internet Explorer, but Yahoo and Google's pop-up blocking software are similar.
To allow pop-ups through Internet Explorer's pop-up blocking feature, which came with Windows XP Service Pack 2:
Click
the yellow bar with the message "Pop-up blocked. To see this pop-up
or additional options, click here ..." that appeared on any of the NHANES tutorial pages. A
context menu will appear. (See screen shot below.)
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.)
Click the Yes button. The page then refreshes - it may appear as if the page 'blinked' - and the yellow bar disappears.
You can now click the link that was blocked earlier, and the pop-up window will open.
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
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, this is what you need to do to allow them.
Go to Tools→Options, and then click the Content tab.
Click the button labeled "Allowed Sites," next to the line labeled "Block Pop-up Windows."
Enter www.cdc.gov in the "Address of Web Site" field. (See screenshot below.)
Click the "Allow" button. (See screenshot below.)
Click the "Close" button to exit the dialog box. (See screenshot below.)
There are additional pop-up blocking software packages available and you may have more than one installed (e.g. XP's pop-up blocker and the Yahoo! Toolbar pop-up blocker). You will need to consult the software's Help section to get help allowing pop-ups from the NHANES web tutorial. Below, are listed some of the more common pop-up blockers and links to their help sections...ions.
You have the Yahoo! Toolbar installed if you see a large red Y!
directly under your browser's Address field.

The NHANES web tutorial also uses scripting to make its contents interactive. This is content that Microsoft Internet Explorer may also be configured to block. When this content is blocked a yellow bar appears directly under the Address field in your browser. This is pictured below.
To allow this blocked content to run, click the yellow bar. A content menu appears. Click "Allow Blocked Content." A dialog pop appears saying Allowing active content like Active X controls and script can be useful, but active content might also harm to your computer. Are you sure you want to allow this file to run active content?" Click the Yes button. The dialog box disappears and the yellow bar disappears. You can now access the active content on this page.
Some of the content in the demonstrations, animations and especially the quizzes, may not appear correctly if you do not have Macromedia Flash 8 player installed. For example, the opening page of the quiz will appear as a mostly blank blue screen and the text identifying the quiz does not appear. To solve this, you will need the Macromedia Flash 8 player. Earlier versions will not work.
Speakers attached to the computer are not required to view the tutorial, but they are necessary to hear the audio narration on the optional demonstrations.
It is available for free from Macromedia at http://www.macromedia.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash&promoid=BIOX. You may need a system administrator to install the software for you if you do not have administrative rights to your computer.

If, while using Mozilla Firefox, you attempt to open an animation that requires Flash player and you do not have it installed, you will see a screen like this:
You can click the "Install Missing Plug-ins" button in the yellow bar to automatically install the plug-in.
Go to View→Text Size→then select the "Larger" or "Largest" option from the pop-up menu.
Go to View→Increase Font. Repeat until the type is size is to your liking.
Go to View→Text Size → Increase. Repeat until the type is size is to your liking.
The tutorial was designed to fit width-wise on a 800 by 600 pixel screen without left-to-right scrolling. However, you will need to scroll vertically. The animations and pop-up windows were also designed to fit inside a 800 by 600 pixel screen without any scrolling. If you do not know your monitor's resolution, you may want to check it before beginning the tutorial.
To check your monitor's resolution on a computer running any version of Microsoft Windows:
800 by 600 pixels is the minimum to use the tutorial, and 1024 by 780 pixels is recommended.
