Sorry I'm not likely to be of use as I am having exactly the same problem. Sometimes if you refresh it will reset and if you delete your temporary internet files etc, but then sometimes it wont!
If you do find a soloution please let me know becasue I am waiting to host my e-learning and I cant until this is resolved because it renders the package unusable!
I am considering taking drastic measures such as going into the HTML and adding some JS to reset it but Im not even certain that this will work on an elearning platform.
It seems unbeleivable that this has been published with such a glaring oversight! There must surely be a simple soloution!! mustn't there??
