That wasn't quite what I was hoping to hear. We have a few courses starting next month and we can't control their version of IE. I'll have a dig around in the code and see what could be causing the error, IE7 should have some decent reporting tools, being the new 'security' rich browser.
I've seen the Reload player, it is nice, I use the editor for creating my content to start with.
I'm sure we're not the only ones using LORS? I'm surprised no-one has flagged this before!
