Two IAT web scripts that I have used successfully in the past have stopped working. After the opening screen (Start button), the screen goes white. Hitting any key on the keyboard stops the program. The script is set to bring the user to a QuestionPro questionnaire, which it then does correctly, but only after briefly showing the opening screen. We have tried it on various browsers and Windows OSs.
Check your scripts thoroughly for issues such as https://www.millisecond.com/forums/Topic7306.aspx#7306, https://www.millisecond.com/community/forums/p/2133/7260.aspx#7260 or https://www.millisecond.com/community/forums/p/1975/6625.aspx#6625. It's very likely you've introduced some simple mistake which leads to the scripts running nothing at all (in a technically correct sense). Let us know what you find.
