You can fix this default by taking one step. Open IE, navigate to Tools, Internet Options, and then click the Settings button in the Browsing history section. The form looks like:
When you click on the Settings button, you’ll come to the following screen. Click the radio button for “Every time I visit the webpage,” which will ensure you get a working grade book in Blackboard.
Click the OK button. You’re not done yet. You must shut down all IE sessions and re-launch the product for the changes to occur. If you think that was tedious, here we need to do it every time our corporate governance folks push an update to Windows because they reset IE to an incompatible set of values for Blackboard’s AJAX implementation.
