Everything we know about Cornerstone on Demand and Storyline!

I have suffered for many months close to years with courses displaying blank pages or partial page loads. with 1.2, 2004, 3rd ed, etc.  Cornerstone, or even other LMS's I don't have an answer for you as we perpetually have to advise our clients to create a work around - like, reassigning the course or refreshing the page.  One item of note is that a page with an animation on it tends to hang up the most frequently and the easiest work around is to grab the seek bar and scrub it - and the page tend to complete loading.  Where we ran into deadlocks was when we tried to get clean and fancy and delete unnecessary player control elements on a slide, like who needs a seek bar on a main menu page?  Especially if there is no audio to play?  No seek bar, nothing to clear the error and nothing to allow a learner to progress in a course...so we have started adding them back into the courses and instructing learners that this is a method to address the problem on their own.  I know Articulate has been looking into this issue for as many months as I have reported it, but it has been a perpetual and inconsistent error.  I hope this give you some insight and you are able to share your experience so that maybe we can find the hidden element or elements that create the perfect storm and cause a course to hang up intermittently.
