We are currently in the process of removing the iframe design and replacing with a more Web 2,0 Ajax framework. We apologize in advance for any problems. They will hopefully be temporary and lead to a more responsive and usable system.
We hope to have the course completed by the end of the year, including student tracking, reporting, and more organized course content.
The system is still free. Please use it with your students and continue contacting us with comments and bug reports.
