A puzzle-course not playing properly on just a few machines in IE
Ok, so we have a Storyline course which works beautifully for 95% of our learners in our PeopleSoft LMS. However, there are a few using Internet Explorer 8 that, when viewing one slide with objects that fade in/out, can't get the next button to enable. They are NOT seeing the fade in/out actions. The next button is set to enable when the timeline ends. The slide acts like it's getting stuck before the Storyline animation begins...all it is is using the timeline to fade/in/out, nothing fancy.
The course always works with Firefox. We've had similar issues in the past with IE9/10 and still haven't been able to find that solution either.
I'm 99% sure it's not Storyline. I've tried clearing their cache/temp internet files with no luck. I've done a system report on the troubled machines and compared them to the working machines with no glaring differences. I'm thinking it has to be something within IE, but there's so many settings/options, where do I begin?
