Toolbook productions exported to html tend to have very specific browser requirements either imposed by Toolbook itself or as a consequence of the production. I originally found that support was very difficult so I devised a testbrower module that users could run to determine their browser's readiness to use the lessons created by Courses by Wire. It has evolved as requirements changed and ability to detect various capabilities were discovered.
I am offering it for download for other Toolbook users to use as they see fit. From time to time as in the past I may change or update this script. If you have any problems or questions you can contact me.
