User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6

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.

@Reporter, we have not heard back from you in a while, so I am closing this bug as INCOMPLETE. You can reopen this bug if more information becomes available. Some helpful information you can provide us is found at http://quality.mozilla.org/bug-writing-guidelines. You should also use a recent version of Firefox, from http://www.getfirefox.com.
