Web Browser Compatibility

Issue: Users with Internet Explorer 8 or below experience sluggish webpage loading and may receive a script error upon entering the FLIGHT site that states: "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?".

Workaround: If you receive the script error message, click "Yes" and proceed with one of the two workaround options listed below to resolve this issue:

  • Option 1. Update Internet Explorer to version 9 or higher.  (NOTE:  If you are using Internet Explorer version 9 or higher and the FLIGHT webpages still aren't loading properly, then make sure you do not have compatibility mode on.)
  • Option 2. Use a different browser such as Google Chrome or Firefox
Issue Pasting FLIGHT URL into Email or Document

Issue:  In Firefox, the URL displayed in the browser’s address bar does not replace spaces with the URL-encoded characters “%20”.  Meaning, the URL can include spaces.  If a user were to copy the URL and paste it into an email or other document, the text would be recognized as a URL and converted to a link.  If the URL was copied from Firefox, the link in the email might be cut off at the first space and not include the entire URL.  So, if a recipient of the email clicked the link, they would not be taken to the correct page.

Workaround:  There are a number of options to get around this issue if you want to paste the URL into an email or document.

  • Option 1.  Use a different browser such as Google Chrome or Internet Explorer.
  • Option 2.  After pasting the URL into your email or document, replace each space in the URL with “%20”.
  • Option 3.  If you are pasting the URL into a Microsoft Office product, then highlight the entire URL you pasted.  Right-click and select Hyperlink.
  • Option 4.  Click the Share link at the top of FLIGHT.  This will display a pop-up.  On the pop-up is a shortened version of the FLIGHT URL.  You can either copy and paste this URL into your email or document or you can click the Share button and select a means of distributing this link to other people (e.g., Email, Facebook, Twitter, etc.).
