Storyline Suspend Data Compression
Oh, and I can say that I have run into issues like you describe with the stuck loading prompt in the past. Usually it has turned out to be some odd event that failed upon resuming. One of the best troubleshooting things in this situation is to have the user who experienced the problem (loading stuck) open their browser developer console (usually Ctrl-Shift-I on most browsers or right click then inspect). All the browser errors are logged to that console, and though there are often lots of warnings and other errors going on, there may be a tell-tale error message that could help you down the path to a solution (or at least with what's going on that's preventing it from completing the resume).
Thanks for the in-depth answer. I'm definitely going to test the compression patch for suspend data in Moodle using SCORM 1.2. As for the odd loading event, I was able to inspect a frozen activity and in console I was shown an error that was not thrown in the same activity that's loading for another student. I'm currently chasing this down and it seems promising. Might fix a bug that has been an annoyance for some time.
