This warning can occur when a student uses their device's touchpad with a three-finger swipe in an attempt to access another application running in the background on the computers. This can also occur if they use the ALT/TAB key combination.
Students will sometimes do this to cheat on their exams. But it can also be an innocent mistake on the part of the student.
Please see the below explanation on how LockDown Browser handles this.
*****************
* During an exam attempt, the 1st time a student switches away and accesses another app (and it takes focus), then returns to LockDown Browser, they get a warning pop-up not to do it again or the browser will shut down.
This is by design in order to avoid false positives. The second time a student switches away and returns to LockDown Browser, LockDown Browser shuts down.
* Once the browser session is terminated, an early exit notification is sent to the instructor's LockDown Browser Dashboard telling the instructor that the student tried to leave the browser. This notification only gets sent upon the student starting a new LockDown Browser session after the shutdown has occurred.
Note: It's important to remember that this handling only ever gets initiated if/when the app being switch to actually takes focus. In many cases, LockDown Browser will kill the app quickly, giving the student no opportunity to interact with that app. If so, our "swipe away" handling will not be implemented and the LockDown Browser session will probably stay active.
* For Blackboard, our testing shows that a quiz attempt is not used if a student's LockDown Browser session is terminated due to a second use of a three finger swipe. This was tested using single attempt quizzes. In each case, we were able to start a new LockDown Browser session and resume the quiz. However, the LockDown Browser Dashboard is sent a message alerting the instructor the action has occurred twice.
There is one exception:
A quiz using Blackboard's "Forced Completion" setting will indeed submit the quiz and use an attempt after the browser is closed on the 2nd three finger swipe attempt.
An early exit notification is sent to the LockDown Browser Dashboard telling the instructor that the student tried to leave the browser. This notification only gets sent upon the student starting a new LockDown Browser session after the shutdown has occurred.
