Let me tell you....if it were not for the Full Screen ability via this small 'hack', I would have not used Articulate. I ran into the same problems of not having the tab load. As a temporary solution, I was advising students to refresh their browsers once they loaded the course. This was not a great solution....but it did work.
In the meantime, I went back to eLearning Enhanced and asked James for some help. He advised me about the 'Tab Pre-Loader'. Although I don't know exaclty how it works (James, if you could assist), I do know that it works flawlessly!
Here is a link to eLearning Enchanced page that has the information. Yes...it costs $100 but it was worth every penny!
I hope that helps a little. The link will describe how it works.
