How to Allow Pop-up Windows from www.cdc.gov
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 other tutorial content. 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.
To allow pop-ups through Internet Explorer:
After clicking a link to a blocked pop-up window a yellow box below the URL/Location field at the top of your browser appears with the message "Pop-up blocked. To see this pop-up or additional options, click here ..." Click the yellow box. A context menu will appear.
Select 'Always Allow Pop-ups from This Site.' A dialog box appears asking "Would you like to allow pop-ups from 'www.cdc.gov'?".
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.
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.)
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.
Microsoft Internet Explorer only
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 and animations, may not appear correctly if you do not have Adobe Flash player installed.
It is available for free from Adobe. You may need a system administrator to install the software for you if you do not have administrative rights to your computer.
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.
Microsoft Internet Explorer
Go to Page→Text Size→then select the "Larger" or "Largest" option from the pop-up menu.
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:
- Right-click any open space on your computer's desktop to bring up a pop-up menu.
- Select Properties from the menu, and then select the Settings tab.
- Under the Settings tab, you should see a slider labeled Screen Resolution.
- 600 by 480 pixels
- 800 by 600 pixels (minimum for viewing tutorial)
- 1024 by 780 pixels (recommended)
- 1280 by 1024 pixels
800 by 600 pixels is the minimum to use the tutorial, and 1024 by 780 pixels is recommended.
