This is a bizzare issue that apparently the students have been dealing with since 2007. If a slide in a presentation is > 8:48, if you try to skip ahead or go back within the 8:49-end time range the player says it is playing (as in, the pause button is visible), but makes no progress through the presentation or audio. We have tried it on Firefox, Chrome, Safari, everything.
Is this a common issue? Is there a way to fix it, beyond rerecording the audio to keep it under the 'magic' threshold?
