FMR slides showing up blank in Chrome

I have a project with some screen-capture slides that use FMR for screen scrolling. There are no issues with these slides in our HTML5 output when viewed locally. However, users of the version loaded on a server are reporting that the FMR portions of slides are showing up as blank white screens in Chrome but not in Firefox on both Mac and Windows.

You can see the published project at https://teach.mapnwea.org/impl/captraining/StudentTutorialNE/index.html

Unfortunately, the issue doesn't appear until you are a ways into the tutorial. The first place that you can see it is picking choice 2 on the tips slide.

Any clues as to what settings we might look at to alleviate this issue?

For HTML output I try to avoid FMR slides whenever possible, or replace them by video demo slides. I hope that it will be come easier in the future to replace FMR by Video Demo slides.

Unfortunately, removing them isn't an option for this particular project at the moment (we'll do it next year.) Any ideas of what might be causing it or how to alleviate it?

i just went through the output, and the FMR slides are converted to .mp4. There are no .swf files anywhere in the directory.

I know using Video Demo is preferable, but that isn't an option for this particular file this year as it's already in use and there's no time built into the schedule for it this year.

If these MP4s are the same bits that do not appear at runtime from your LMS, have you checked with your LMS Server Administrator to make sure that MP4 files are allowed to be served? MP4 may not be enabled by default and that might be causing your issue with blank spots appearing instead of the animated sections.

Just a thought.

EDIT: Just noticed up the top of this thread that you said it worked in other browsers but not in Chrome. If so, then the web server must have MP4s enabled already. So my suggestion may not be valid.
