How to fix exam issues caused by IE8
If you are having issues while you are taking your exams, such as the timer box scrolls up and down the webpage and prevents you from clicking the submit button, then follow the below steps to fix it.
Internet Explorer 8 is a new release and some websites may not yet be ready for Internet Explorer 8. Click the Compatibility View toolbar button to display the website as viewed in Internet Explorer 7, which will correct display problems like misaligned text, images, or text boxes. This option is on a per site basis and all other sites will continue to display with Internet Explorer 8 functionality. To go back to browsing with Internet Explorer 8 functionality on that site, simply click the Compatibility View button again.
Try clicking the "Compatibility View" toolbar button to fix the problem. It's located next to the Refresh button on the Address Bar.
You can maintain a list within Internet Explorer 8 for sites that should be displayed in Compatibility View. From the Command Bar, select Tools, and then select Compatibility View Settings to add and remove sites from this list. There are also options for viewing all websites and intranet sites in Compatibility View by selecting the last two check boxes depicted in the below picture.
