My college uses the Blackboard Academic Suite for my classes. When I navigate to the assessment/quiz input area (JavaScript), Firefox hangs and occasionally causes 100% cpu usage. The same page works fine in IE6 with the same JRE.

Copied from the Java Console:

Warnings in the Error Console, repeated several times:

Warning: reference to undefined property h.cmp_field
Source File: http://ilearnapp2.grcc.edu/javascript/validateForm.js
Line: 91
Warning: reference to undefined property h.display_format
Source File: http://ilearnapp2.grcc.edu/javascript/validateForm.js
Line: 65

This may be a general incompatibility error between JRE and FF that happens at multiple sites, but this particular one is the most critical to me right now.

Reproducible: Always

Steps to Reproduce:
1. Open any page using BlackBoard Academic Suite
2. Navigate to assessment/test/quiz of choice

Actual Results:  
Firefox hangs (usually), menu behavior is corrupted (sometimes), window responds incorrectly

Expected Results:  
I should have gotten an input form to complete an assessment/test without crash or hang.

If there is a way to copy the entire error log (rather than one line at a time), please tell me how to do so.
