You may have to reload the page or the browser for the change to take effect.

To always display this content, you can change the setting in the Internet Options.

1. Click on the Tools menu item from the menu bar in Internet Explorer 9.
2. Choose Internet Options from the menu.

Google Chrome

Google Chrome has a few known issues in Desire2Learn.

"Duplicate Headers" Error

Sometimes when downloading a file in Desire2Learn using Google Chrome, students will get an error message regarding "duplicate headers." The only known solution to this is to use a different browser.

Quizzes

Students may also run into an issue in which the Submit Quiz button is not displaying while they are taking a quiz. If you encounter this issue, it is recommended that you make sure your answers are saved and that you have time to finish the quiz. Open Desire2Learn in another browser and try to re-enter the quiz by clicking Continue Quiz and then submit the quiz.

Safari

Turn Off the Pop-Up Blocker

Safari doesn't natively allow you choose which sites to block pop-ups on. It only features on or off settings. It is recommended that you turn off your popup blocker while using Safari to access Desire2Learn and turn it back on when you are done accessing Desire2Learn.

1. Click on the Safari menu item from the menu bar at the top of the screen.

2. Click on the checked "Block Pop-Up Windows" option to turn off the pop-up blocker. If there is no checkmark to the left of the "Block Pop-Up Windows" option, then your pop-up blocker is already turned off.

Repeat these steps to turn the pop-up blocker back on after you are done accessing Desire2Learn.
