Screen Freezing When Using Pause Button and Slidebar in IE11 Windows 7

Mar 15, 2018

With a published Storyline 3 file, there is a bug that will freeze the entire page in our LMS, specifically in IE11 on Windows 7. This occurs—inconsistently—when interacting with the play/pause button and the scrollbar. 

After the bug occurs, there is no error in the dev tools console. The audio for the screen finishes playing normally, but all buttons become entirely unresponsive, including the exit button of our LMS (which is in a different frame than the Storyline content). This behavior leads me to believe that there is an infinite loop occurring in the Javascript code.

Using the debugger, the code seems to always break at the following location of app.min.js (tested in 2 versions of Storyline 3):

Version 3.2.13213.0 / Line 17, Character 5155 (search "function(e){E=P()")

Version 3.3.15007.0 / Line 19, Character 14933 (search "function(e){A=C()")

If you look at example-1.mp4 you will see the glitch occur between 6 and 7 seconds. I was doing mousedown - move mouse - mouseup for this example, which seems to cause it more often. However, I have also made the bug occur with a simple triple-click, as well (see example-2.mp4 at 36~37 seconds).

Hi Kenneth,

It sounds like you've had a few issues with IE content and freezing, as I also saw you reached out here.

Have you also looked at where it's being hosted and tried it somewhere else, such as uploading to SCORM Cloud? I know a few LMSs are forcing IE content to display in a compatibility mode which is causing issues with the HTML5 playback. Do you know if that's something your LMS could be implementing?

If you test it in SCORM Cloud and it shows the same freezing, could we get a copy of this .story file to test it?
