Next button not appearing on rare occasions
I have a slide that the user needs to open 5 documents on before the next button will appear. The first trigger changes the state of the next button to Hidden when the timeline starts. I have then set up a variable called ShowNext that is set at zero initially and is incremented by 1 each time a document is opened. I then have another variable ShowNextTF that is initiated as false and change to true when ShowNext reaches 5. I hope you are still with me. My final trigger is to change the state of the Next button to Normal when ShowNextTF changes.
Ok all works fine, I have tested it in a number of browsers and different LMS environments all works as it should. I then set up a pilot program with a small group of people from different locations and all with different PCs (about 60 people in total) in most cases the functionality works fine, however, I have two users where the Next button simply does not appear. I have checked operating systems and versions of Chrome all are the same, I am thinking it could be a browser setting or something on the individuals PC as it works almost everywhere else.
If anyone has any ideas or thoughts on this it would be appreciated.
