Well, what fun. I was hoping that would fix it. There is something else you can try. Basically what I think is happening is that for some reason the course is running from a local zone which has different security settings than an internet zone. So you get a warning when something locally tries to contact the internet (even though that's not techinically what's happening in your case). You can try and fool your browser into thinking that it is being run from an internet location by adding a Mark of the Web tag to each page. The easiest way to do this is to add an external HTML object at the title level - select "Header Scripting" for the type and put: In the custom html box. That should place it between the tags of the page (where it should go) and make flash think that it's already in an internet enabled location. Do some testing though - it should fix the flash error but could cause problems with tests and quizzes - which I'm not sure why. Let me know if it works.
