**I am working on a Windows 7 machine. I can't get the above problem to work. In Firefox and IE I get the popup message below. On Chrome I get a similar message.**

**Is there a security setting I can 'fix' to be able to see this problem? Even so, I suspect students will run into the same issues. Does anyone use this problem and get it to work?**
