Hi erlend,

I am unable to reproduce the issue on my end (Safari Version 10.0.3 (12602.4.8). Can you reproduce this issue on a different Mac? Can you check for other plugins in Safari that may cause this problem.



I can reproduce this with erlend's example.  But only if I immediately skip to halfway through the video after starting and do not answer the first question.

If I skip back to the first question and answer it then the video continues and can skip forward or back without error.

Thanks adding a bit more information. I've created an issue here:


It seems to occur on Safari 9 but not 10 or the ones before. It is a pretty serious bug and should be addressed in this or the next release.
