Teaching Record Broadcasting System

Teaching Record Broadcasting System (TRBS), http://www.4edu.com.tw/english/product/trbs.php , is a software solution that broadcasts the teacher's screen to all students' monitors. We believe that TDHelp32.exe, the app that runs in the background on the student and teacher's computers, is either replacing the system's OpenGL32 dll with its own version or hooking into the OpenGL pipeline in order to allow the instructor to “broadcast” to the student's computer. There is a problem/bug in their software that is conflicting with Rhino's OpenGL usage, and causing Rhino to crash. The work around is to terminate TDHelp32.exe in Windows Task Manager before running Rhino. Apparently this does not affect the broadcasting system and the teacher is still able to send his screen to the students' monitors.
