Securexam saves your answer every minute and checks if the file contains data. If you have opened up an answer tab and after 15 minutes have not typed anything, Securexam will warn you with this message:
Empty Document – Nothing Typed Warning! The system has detected that 15 saves and/or minutes have occurred without any text being typed. If there is text appearing on your screen in the document right now – STOP IMMEDIATELY and get a proctor before proceeding. If your document is blank and you have not typed any text yet and wish to continue, click on “Okay to continue”
This message will also appear if you typed only in the spreadsheet tab since Securexam is looking for content in the answer tab.
To prevent this message from appearing, when you open an answer tab, simply type the question number or just one character.
