In order to deliver the OpenMath technology to the classroom with supporting resources, browsers were needed. Unfortunately not all of the popular browsers were capable of handling JavaBeans or Java v1.1 applets. Microsoft's Internet Explorer v4.0 provided the most reliable support. However it failed to work with some of the later applets developed in Phase II, at which point the appletviewer from JDK v1.1.6 was used. Using appletviewer discounted the use of supporting HTML text and images in the lessons presented to the students.
