I periodically review your tutorial films to update my skills. I use Opera (now 8.54) as my preferred browser. I was able to view a Brainstorm Java model and navigate successfully but the Find button gave Opera fits, flashing the screen without finding the term.
I opened the file in Firefox (1.503) and viewed the model successfully in all modes. The model would not open in Internet Explorer, 6.0.2900. I got the Balloon text view.
I tested all browsers with http://www.cubagenweb.org/help/javahelp.htm
and all browsers have Java activated and installed. I've had the latest Java Runtime installed: 1.5.0_06.
